BRIEF OVERVIEW OF THE SUSTAINIAC â STEALTH PRO SUSTAINER
The Sustainiac Stealth PRO kit price is $229.00 plus shipping for the 6-string version, or $249.00 for the new 7-string version. This includes all parts, controls, driver, and circuit board. Options are available. You can order directly from us from anywhere in the world, using the link to the ORDER FORM at the bottom of this page. We take Paypal, Visa, Mastercard, money order, USA checks. The Stealth PRO must be installed into your guitar. Installation requires considerable electronics skill, and can take from 3 to 12 hours or even more for very difficult guitar models. Options and more detailed prices are shown on the ORGANIZE YOUR ORDER page, or the EMAIL ORDER FORM Copy and paste this page into an email addressed to us. Also see link at the bottom of this page.
The Sustainiac Stealth PRO is designed and manufactured by Maniac Music Inc., Indianapolis, Indiana, USA. You can get screaming feedback sustain at any volume at home, in the studio, or on stage. You can "morph" the sustained string vibration into cool-sounding harmonics during a solo, by using the Harmonic Mode control. This allows you to give your solos character and originality in a way that was previously only possible by getting feedback from your amp at dangerously loud levels. It is similar to amp feedback, except that the feedback sustain is more predictable and much easier to achieve.
The Sustainiac Stealth PRO sustain system drives the strings of an electric guitar into infinite feedback sustain of string vibrations by electromagnetic feedback. You control the feedback sustain by simple hand muting. Also, you don't have to blast your ears with dangerous sound levels of a large amp. It doesn't change the tone of your guitar pickups or output signal, because it operates directly on the instrument strings. Hear examples on the SOUND PAGE. Go to the PERFORMANCE SECTION for more info on using the Sustainiac Stealth PRO sustainer in performance.
Many people mistakenly refer to our "Sustainiac pickup", because all they see from the front of the instrument is the magnetic string driver. This driver does resemble a pickup in appearance. But the Sustainiac Stealth PRO sustainer is much more than this. It is actually an electromagnetic sustain system that contains three main parts.
The Sustainiac Stealth PRO contains the following features (more details in the next section):
A list of DETAILED TOPIC LINKS is contained at the bottom of this page. These are links to various pages that go into detail about certain aspects of installing and using the Stealth PRO. An INSTALLATION PAGE contains installation explanations and diagrams for specific guitar types and models. This page is linked frequently in the website, because it is so important. It also tells you about things that might make a guitar unsuitable for an electromagnetic sustainer. When you think you might be about ready to order, there is a page for Organizing your order. This organization outline should help to eliminate the confusion that often arises over the many available options.
The sustainer taps in to your bridge pickup signal (without changing in any way the signal that goes on to your guitar amp), amplifies and processes this signal, then sends this amplified/processed bridge pickup signal to the magnetic string driver transducer. The transducer sends out magnetic pulsations in response to the bridge pickup signal. These magnetic pulsations cause the string vibrations to be sustained. When the sustainer is OFF, the driver transducer functions as an active neck pickup. When the sustainer is ON, the bridge pickup is automatically selected, bypassing the pickup selector switch. When the sustainer is OFF, the pickup selector switch and the rest of your guitar function as before.For an in-depth discussion, go to the OPERATING PRINCIPLES
The Sustainiac Stealth PRO has evolved from our earlier electromagnetic sustainers GA-1, GA-2 (late 1980's, installed into thousands of Hamer, GTX (Kaman), and Fernandes guitars, Sustainiac Stealth model (1999), and Stealth PLUS model (2001). Starting with the Stealth kit in 1999, we began making our kits "stealthy", with the controls separate from a small microelectronics circuit board. This allows you to install the unit into most electric guitar models without having to do any routing. So, you can restore the guitar to its original condition if you want. Our sustainers are the only commercially available sustainers with this capability.
We set out to design the Sustainiac Stealth series of sustainers to solve the main problems of all previous sustainers. This included both problems of sustainer performance, and also practical problems with doing the installation into existing guitars. The new Stealth PRO can be installed into most popular electric guitars with NO ROUTING in most cases, or minimal routing. We have revolutionized magnetic sustainers with the Stealth PRO sustainer and its predecessors.
INSTALLATION KIT CONTENTS AND PRICES
The installation kit sells for $229 plus shipping. ($249 for 7-string version) This includes all parts, controls, driver, and circuit board. Options and more detailed prices are shown on the ORGANIZE YOUR ORDER page, or the SECURE ORDER FORM also see link at the bottom of this page). You can order directly from us. We take Paypal, Visa, Mastercard, money order, USA checks. A photo of the kit can be viewed: Low resolution kit pix (8kb); High resolution kit pix (71kb)
ELECTROMAGNETIC STRING DRIVER TRANSDUCER: Click here for driver options picture: Low resolution driver pix (11kb); High resolution driver pix (55kb) The driver usually replaces your neck pickup. (In some applications, it can replace the bridge pickup. For instance, a lot of Strat players depend mostly on their neck pickup. In this case, you must mount the bridge-position driver so that it no longer is slanted.) It can not replace a middle pickup in a 3-pickup guitar, however. It will be too close to the other pickups, and the sustainer performance will be severely affected. We need 3 inches MINIMUM spacing between bridge pickup and Sustainiac driver (measured center-to-center). 3.5 inches is even better. The driver emits electromagnetic pulsations in response to the instrument string vibrations. These electromagnetic pulses cause the string vibrations to sustain by magnetic force. When the sustainer is OFF, the driver functions as an active neck pickup. One of the two "trimpot"controls on the circuit board allows you to set the neck pickup volume to match most any bridge pickup on the market. One new feature of the Stealth PRO is that the active pickup sound can be set for a bright, single-coil like sound (although it is hum-canceling), or a darker humbucker sound by connecting a wire to ground. You can also boost the output level by 3dB by connecting another wire to ground. Or, a switch (toggle or push-pull) can be installed so that you can switch back and forth between these sounds. Drivers are available in single-coil (SC) size or humbucker (HB) size. Color choices are black or white. (Black only for 7-string driver) You choose the size and color when you order. The HB-size driver is identical to the SC-size driver, except for the size of the baseplate that it is mounted on. Also, we stick a plastic "dummy" cover onto the HB driver cover to make it look more like a regular humbucker pickup. Both the HB and the SC driver have identical sound as a pickup, because this is determined on the circuit board. They also both perform identically as a driver.
SIX-STRING DRIVER: The driver height is 0.85 inches (21.6mm) for both HB and SC. HB baseplate width is 1.375 in. (35mm), SC width is 0.7 in. (17.8mm). Length of HB is 3.325 in. (84mm), SC is 3.23 in. (82mm). See PDF file for 6-STRING DRIVER DIMENSIONS.
SEVEN-STRING DRIVER: The driver height is 0.85 inches (21.6mm) for both HB and SC. HB baseplate width is 1.375 in. (35mm), SC width is 0.7 in. (17.8mm). Length of HB is 3.73 in. (94.7mm), SC is 3.75 in. (95.3mm). See PDF file for 7-STRING DRIVER DIMENSIONS.
ABOUT THE PICKUP SOUNDS:
SINGLE COIL SOUND: The sound is very similar to a Strat neck pickup, but with virtually no hum. The blend of the neck pickup with a typical single-coil middle pickup does not give as good a "quack" sound as a real single-coil combination, but the main "quack" sound is the bridge/middle combination anyway. Blues players tend to love the neck pickup sound.
HUMBUCKER SOUND: The humbucker sound is very fat, similar to a stock "59" sound, but can have much higher output if you turn the trimpot control up high. Also, it has noticeably less hum than a typical passive humbucker. You can make it darker by adding a resistor or pot between one of the circuit board wires and ground (see Installation page for specific info on this).
The driver design of the Sustainiac Stealth PRO is unique. Its patented bilateral design makes magnetic field cancellation from the driver nearly perfect. This means we can set the sustainer gain higher than with other sustainers in the marketplace before the closed feedback loop oscillates (squeals). This is the main thing that sets the Sustainiac sustainers apart from all of our competition, achieving strong, consistent sustained string vibration with most all guitar types. Read the many unsolicited user reviews on HarmonyCentral.com and various chat-groups.
CIRCUIT BOARD: The Stealth PRO circuit board measures 3.75in. x 1.1in. x 0.5in. thick (95mm x 28mm x 12.5mm). See this PDF drawing: Stealth PRO circuit board dimensions It runs on a single 9-volt battery. You install the board inside the electronics cavity of your electric guitar. It must be electrically connected to your pickup selector and sustainer controls. Complete installation instructions and diagrams come with each kit. The circuit high impedance input is connected to your bridge pickup. It amplifies the bridge pickup signal, and does other electronic processing to it. It then applies this amplified, processed bridge pickup signal to the electromagnetic driver. Your raw bridge pickup signal goes on to your other guitar effects, amp, etc. with no processing or change in its original sound. When the sustainer is OFF, an amplifier circuit on the board amplifies the driver signal, enabling it to be used as an active neck pickup. Click here for a WIRE FUNCTION DIAGRAM, showing the function of each color-coded wire. When the Sustainiac is OFF, the Sustainiac driver is used as an active pickup. The sustainer circuit now amplifies the tiny driver pickup signal to a useable level. Pickup equalization is done on the circuit board. Two wires are provided to allow switching between single-coil (SC) and humbucker (HB) sound. These are the white/violet wires on the 10-pin connector. If you connect the white wire to ground, it boosts the gain by about 4 dB. Connecting the violet wire to ground rolls off the highs. If neither wire is connected to ground, then the default sound is SC. If you want to use this function to switch between SC and HB, simply connect both wires to ground with a toggle or push-pull switch.
The Stealth PRO uses a unique, patented "class D" amplifier to drive the strings into intense sustained vibration, while using only a small amount of power from the 9-volt battery. It is the combination of this circuitry along with the patented bilateral driver that sets the Sustainiac Stealth PRO apart from our competition. You get stronger, more consistent sustain from instrument to instrument.
TRIMPOT CONTROLS: Screwdriver adjust on circuit board: (1) Sustainiac gain; (2) Neck pickup volume; (3) Harmonic Mode gain, new mini-pot (July 2009) allows you to set gain of Harmonic mode only
When the sustainer is turned ON, the bridge pickup is automatically selected, regardless of the position of the pickup selector switch. It HAS to be this way, because the driver must be physically distant from the pickup that provides the input signal to the sustainer. Otherwise, uncontrolled oscillation (squealing) occurs. (Similar to having a microphone too close to the speakers in a PA system.) When you turn it OFF, the pickup selector goes back to normal function.
The Sustainiac ON/OFF push-pull control uses only the switch portion of the control. Therefore, its pot portion functions as the original guitar control that it replaced. The HARMONIC MODE control uses both the pot and the switch portion of the control, so the control that it replaces goes away. For a 2-pot guitar, you will lose either the volume or the tone control, unless you are willing to drill a new hole. If you choose toggle controls, you will likely need to drill new holes in the front of the instrument.
Sustained string vibration can be "morphed" into different cool-sounding harmonic modes. This enhances your solos in ways that were not previously possible. You get all 3 modes (see below) whether you choose the standard push-pull control, or the 3-position toggle control. The push-pull control option allows the same control to serve as a sustain intensity control, and also produce all 3 harmonic modes. With the 3-position toggle option, you can add an optional sustain intensity control pot (new feature with the Stealth PRO).
Which type is best, push-pull or toggle? Each type has its own advantages. For most professional musicians, toggle controls are generally best. They are faster to access during a solo. But, you usually have to drill new holes in the guitar body to mount toggle controls. If you choose push-pull controls, you can restore the guitar to its original condition if you decide to sell it. One thing to consider: It is most important to have fast access to the ON/OFF switch during a solo. Toggle is best for this. But once you have a note sustaining, you have some "leisure time" to change the harmonic mode of the note, because at this point you are just holding a long note. So, the push-pull can be good here, especially since it has a built-in sustainer drive control.
Go to the CONTROLS PAGE for more info on the different options for Sustainiac Stealth PRO sustainer controls.
9-VOLT BATTERY AND OTHER POWER SUPPLY OPTIONS
You will get about 15-40 hours on an alkaline battery, depending on how much you actually use the sustainer. Don't use the cheaper "dry-cell" or "long-life" (actually just a dry cell). These are a little less expensive than alkaline, but the shelf life is only about one year, and they lose capacity much faster than alkaline. You pay less for total "sustain time" using alkaline. A 9-volt alkaline battery has about 500-600 milliampere hours of energy. When the sustainer is sustaining a note, battery current drain is about 50 milliamperes (ma). So, you should be able to hold a long note for about 10-12 hours. Call Guiness BWR first! When hand muting with the sustainer ON, current drain is about 10ma. When the sustainer is turned off, current drain for the active neck pickup is about 2ma. You can get a good estimate from this info. No battery current is consumed until you plug a mono guitar cord into the guitar output jack.
DO NOT PUT TWO BATTERIES IN SERIES TO MAKE 18 VOLTS. Certain components on the Sustainiac circuit board might fail. Also, the neck pickup only functions between 7 and 10 volts.
DEAD BATTERY INDICATION: When the battery voltage decays to about 7 volts, the neck pickup will stop functioning. At this time, the battery is almost "dead". The sustain function will continue down to about 5 volts, and will get weaker and weaker as the voltage continues to decay. Strange pulsations are also likely to occur at this low voltage. If you take the battery out (or it dies), the bridge pickup will continue to function. The bridge pickup is direct wired to the pickup selector. So, you never lose its function and become "stranded" at a gig.
OPTIONAL QUICK-CHANGE BATTERY CASE Photo of both single and dual battery cases (31kb);
In our opinion, this is the best portable option. But, it does require that you route a cavity into the back of the guitar body. We sell the single battery case for $16. The dual case is $25. If Maniac Music does your installation, we charge $25 to route this cavity. Click here Gotoh battery case dimensions for a PDF drawing showing the battery case dimensions, and routing mechanical info.
PARALLEL BATTERY CONNECTION: Some people inquire about putting 2 9-volt batteries in parallel to extend battery life. They order our dual battery case for this. This will work if both batteries are NEW AND IDENTICAL (same brand). But we don't recommend it. If you leave your guitar on a stand with the cord plugged in, and don't play for a few days, BOTH batteries will die. If you worry about having the battery die while playing a gig, here is a better idea: Get the dual case but leave one side disconnected. Just use it as a spare battery holder.
USING WALL SUPPLIES ("WALL-WARTS"): You must use a REGULATED supply of 9.0 volts. Most "wall-wart" supplies are UN-REGULATED. This means that they put out 9 volts AT RATED CURRENT. At less current, their voltage goes up to as much as 12 to 14 volts. DON'T USE AN UN-REGULATED SUPPLY. We sell a regulated 9 volt supply for $25. You will have to install a connector on your guitar to accept the supply.
INSTALLATION OF STEALTH PRO INTO YOUR GUITAR:
Installation is not a trivial task. It requires experience with electronics, soldering, following wiring diagrams etc. It will usually take between 3 and 12 hours, depending on the guitar type and the skill/experience of the installer. If you are not experienced, we recommend that you have an experienced ELECTRONICS TECHNICIAN do the work. We offer an installation service on most guitar types. See below for more information on this. We have found that many experienced luthiers are not experienced with technically challenging electrical installations. Question your installer before allowing him/her to proceed. Alternatively, we offer a Semi-Install option , where we do 90% of the work. This is described further down the page.
Refer to our INSTALLATION PAGE for more details on specific guitar models. Lots of ideas are presented, and also hookup diagrams for most common guitar types.
A detailed, illustrated installation manual is included with each Sustainiac Stealth PRO sustainer kit. Click here for a PDF file of our 8-page installation book that we include with each kit.
HAVING MANIAC MUSIC INC. DO THE COMPLETE INSTALLATION INTO YOUR GUITAR:
As an option, Maniac Music will totally install the system into your guitar for approximately $125- $175, depending on the guitar type. We charge extra for routing. For instance, if you want us to install the optional battery case ($16.00), we charge $25 to route the cavity.
Shipping your guitar to Maniac Music: Click here for PDF instructions Shipping guitars.
SEMI-INSTALL OPTION FOR MOST GUITAR TYPES: $75.00-85.00 We do 90% of the work. We supply a completely wired and TESTED set of electronics for your guitar, including Sustainiac circuit board and controls, pickup selector, volume and tone controls. You simply remove all of your existing guitar cavity parts as a "glob", after disconnecting your output jack and pickups. You can then save this "glob" of parts to restore your guitar to its original condition if desired with very little work. We now have a separate webpage that is dedicated to this: Stealth PRO SEMI-INSTALLATION page
On this page of the website, you will see standard SEMI-INSTALLATIONS for the following guitar types:
NOT-RECOMMENDED GUITAR TYPES AND OTHER PROBLEM SETUPS:
Examples of INCOMPATIBLE bridge pickups:
ABOUT COIL-TAPPING: Humbuckers have two coils that are arranged in series in a way that each coil produces an equal-but-opposite response to external magnetic "hum" fields (they "cancel"), and equal but same response to string vibrations. It is what makes them have "hum-cancelling" properties. It also makes them have a sound that is less bright than a single-coil pickup. Many people like to disable one of these two coils by using a switch to short to ground at the point where they are connected together. This gives a pickup that is no longer a humbucker, but a single-coil pickup. The Sustainiac will function with a bridge humbucker having a coil-tap switch. BUT REMEMBER: When we ship a circuit board, we ask the customer to specify whether the guitar has a humbucker or a single-coil pickup. We make circuit boards with two different internal equalizations, depending on which pickup type the guitar has. A guitar with a bridge HB, if used with a Stealth PRO having SC equalization, will have a hot NORMAL mode, but a weak HARMONIC mode. If you have a guitar with SC bridge pickup but a Stealth PRO with HB equalization, you will have a weak NORMAL mode, and a HARMONIC mode that will likely squeal (oscillate) because it has too much gain for the SC bridge pickup. Granted, there is now a separate trimpot for HARMONIC mode on all the Rev. 5.4 and above boards, which will partially compensate. But if you use a COIL-TAP SWITCH, one of the pickup positions will be compromised. This usually doesn't cause any big problem, but we like for people to know what to expect.
ALTERNATIVE HOOKUP FOR COIL-TAPPING:
DRY-RUN INSTALLATION You can do a "quickie" installation on any questionable guitar to determine its suitability. Click here for a PDF file of the whole procedure:"DRY RUN" TEMPORARY INSTALLATION Click here for a PDF diagram: "DRY RUN" DRAWING It takes about 15-20 minutes. Install the driver, and hook up the bridge pickup to the sustainer input, connect a battery and a few other wires to ground. Connect a guitar amp. This will instantly tell you if this guitar will be suitable. We do this on many guitars to save headache/heartbreak. This is only practical for guitars with open-back electronics cavities. Not practical for most pickguard guitars.
Many more details are given on the INSTALLATION PAGE, along with hookup drawings of the most popular guitar types.
COMPATIBILITY WITH ACTIVE PICKUPS, such as EMG etc.
The Stealth PRO kit is compatible with active pickups such as the EMG. etc. The EMG supplies a perfectly good input signal to the Sustainiac. (But its polarity is reversed from most other pickups, so to compensate for this you have to remember to reverse the red/black Sustainiac driver wires.) Be sure to specify on the SUSTAINIAC ORDER FORM that you are running EMG's etc. by clicking on the appropriate button. This is because the output impedance of the pickup amplifier is a little different than for normal magnetic pickups because many people use 25K ohm volume and tone controls with EMG's. If you elect to use push-pull controls, we can supply the ON/OFF control with 25K ohms if you wish. You don't HAVE to use 25K controls as many people think. The advantage of using 25K ohm controls is that they allow you to use a longer output wire before high frequency rolloff occurs. If this is important to you, then 25K is good.
NOTE ABOUT USING ACTIVE PICKUPS: Active pickups hook up just like other pickups except for the battery connection. They have a shield wire that connects to ground (usually a pot body), and an output or "hot" wire. The battery (-) wire must be disconnected from ground when you are "unplugged", or the battery will continue to run all the time. Furthermore, you must use two separate 9-volt batteries, one for the active PU, the other for the Sustainiac. Otherwise, oscillation can result. Since sustainers use up batteries much faster than preamps, when the sustainer battery dies everything will stop working. You might be able to finish a gig with no sustainer, but you will need your pickups! When you have two batteries, you must replace your output jack with a special 9-pin TRS jack.. Click on the PDF file which shows how the jack is used, and why, and how it is hooked up. This 9-pin jack has built-in switches that disconnect both batteries independently when you remove your guitar plug. Be sure to check this on your order form if you use active pickups.
COMPATIBILITY WITH PIEZO-ELECTRIC PICKUPS You can operate the Sustainiac if you select your piezo as the guitar output. Piezo pickups, on the other hand, don't provide a good input signal for the sustainer. Piezos and digital modelled pickups, etc. produce phase shift in the signal which alters the performance of electromagnetic sustainers. So, you must add a conventional MAGNETIC PICKUP INPUT as a bridge pickup for the guitar, to provide a suitable input signal for the sustainer. But, you can use piezos while the Sustainiac is on, and they don't interfere with each other. Same thing for guitars having hexaphonic pickups such as the Roland GK-2a for synths etc. See the next topic for details on this.
COMPATIBILITY WITH GK-2, GK-3 and other SYNTH PICKUPS So, you must add a conventional MAGNETIC PICKUP INPUT as a bridge pickup for the guitar, to provide a suitable input signal for the sustainer. Then it will work OK. Guitars having these special, hexaphonic magnetic pickups located next to the bridge provide a specialized low-output signal for driving hexaphonic synth systems and also the Roland "VG" systems. The outputs of the synth/VG systems generally do not have a suitable phase response for electromagnetic type sustainers such as the Stealth PRO.
Stealth PRO for bass guitar: We have a special version of the Stealth PRO circuit board that allows strong sustain down to the very lowest notes. No extra charge. Just specify on the Order Form that you want it for bass guitar.
HEXAPHONIC MODEL We do not currently make a hexaphonic sustainer. These have six (or 7 etc.) independent sustainers. They allow complete sustain of chords. There are no immediate plans to make one. Occasionally, we get such a request but not very often. The size and complexity of such a sustainer would make the "STEALTHY" concept obsolete. Retrofit of such a sustainer would be a major project. The expense would be quite high. Furthermore, for most soloing, there would not be a great advantage. We may eventually do this, but not in the near future unless the request rate increases.
