FIXING AN IMPROPER INSTALLATION
These two pictures show the main problems that we see with botched installations.
"THE "IMPROPER INSTALLATION" PHOTO SHOWS THE MOST COMMON INSTALLATION MISTAKES. THIS CAUSES US COUNTLESS HOURS WITH CUSTOMERS WHO DON'T
LIKE TO READ INSTRUCTIONS.
- THE MAIN THING TO SEE is that the wiring in the BEFORE picture is much neater than the AFTER picture. The wires are much shorter. Also they are carefully routed to minimize crosstalk.
- The Sustainiac circuit board in the BEFORE picture is oriented BACKWARDS from our hookup diagrams. You ALWAYS want the 8-PIN CONNECTOR to be close to the pickup selector switch.
That is the right-angle connector near the left side of the "FIXED INSTALLATION" photo.
- If you don't do that, then the white and orange wires of the 8-pin connector will have to extend a long way to reach the pickp selector switch as shown in the IMPROPER INSTALLATION photo.
- The white/orange wires both carry bridge pickup signal. They are high-impedance, and therefore can easily "pick up" high level Sustainiac signals from the circuit board and other SIGNAL RADIATOR wires.
This creates "CROSSTALK". This results in UNCONTROLLED OSCILLATION (SQUEALING).
- Notice the violet/gray twisted pair in the FIXED INSTALLATION photo. It has been moved to the top side of the photo, well away from all guitar signal wires, controls etc. The violet/gray pair are
SIGNAL RADIATOR wires. By moving them away from all other wires and contacts, the wire pair cannot cause crosstalk.

OVERVIEW OF THE INSTALLATION PROCESS OF THEâ STEALTH PRO SUSTAINER
A list of INSTALLATION OPTIONS AND DETAILS is shown at the bottom of this page. Links to PDF installation drawings of specific guitar models are shown, as is a PDF copy of the installation manual.
But first, read the following few paragraphs for an installation overview.
The Sustainiac Stealth PRO sustain system is a retrofit sustainer for existing electric guitar. The installation requires substantial rewiring of the guitar electronics cavity. For most installations, no routing or drilling of
the guitar electronics cavity is required if you use the standard two PUSH-PULL POT/SWITCH controls for ON/OFF and for Harmonic Mode that are supplied with the kit. If you choose the optional TOGGLE-SWITCH controls to control the Sustainiac, you will likely
have to drill holes in the guitar body. If you are familiar with electronics assembly, soldering, and following wiring diagrams, you can likely handle the installation. It is much more difficult than, say, replacing a pickup or volume control.
Many guitar technicians can handle the installation, but many call us for help. An excellent woodworker isn't necessarily equipped to handle an electronic wiring job of this complexity. Know your technician before letting him/her take this project on.
It will usually take between 3 and 10 hours, depending on the guitar model and the experience of the installer and the guitar type. Pickguard guitars take longer. Parker Flys take many hours.
Alternatively, you can have Maniac Music do your installation. We 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 $25.00 to route the cavity for this.
PRICING for different guitar types:
- The easiest installation is into guitars with electronics cavities that open from the back, and are roomy. This includes most "shredder" type guitars with H-S-S pickup configuration, and many 2-HB guitars. Gibson Les Pauls are
not so roomy but do-able. Generally, these are $125 unless unusual problems are encountered.
- Next in difficulty is any pickguard guitar, such as Stratocaster and Ibanez Jem. We charge $150.00 for these. The problem here is that you have to remove the pickguard to do any adjustment, then fit everything back together again.
It can involve multiple disassemblies/assemblies before everything is working smoothly. Also, we have to remove all the shielding foil from around the pickup area.
A labor-intensive process. NOTE: Newer Jem guitars use a new VLX-91 switch that is wider than the old VLX91. This new wider VLX 91 takes up so much room inside the tiny Jem cavity that the Sustainiac circuit board will
not fit into the cavity. Therefore, we have to create a new cavity under the pickguard for the Sustainiac board. Add $25 if this is the case.
- The Parker Fly (original version with large Fishman board and "octopus" ribbon cables) is $175. The new point-to-point version is a little easier, $150.

PLANNING YOUR INSTALLATION
There are several things you must consider when planning a Stealth PRO installation. Each kit shipment is somewhat custom, based on your particular guitar type. Our kits are not "one size fits all" because guitars are not "one size fits all".
Read the following list, and determine what you need for your particular guitar. These choices are listed on the order form. You will need to make the proper choices to get the proper parts assortment and hookup drawing in your kit. Then, after
you have reviewed everything, you should visit our ORGANIZE YOUR ORDER page when you think you are about ready to place an order. You can print this page, and use it for your guide. It allows you to list and outline your installation plan,
and it makes it easier to navigate the Order Form.
- DRIVER SIZE AND COLOR: The Sustainiac driver replaces your neck pickup. The driver becomes an active neck pickup when the sustainer is OFF. The driver is available in two sizes (HB and SC) and two colors
(black and white). The Sustainiac driver low-resolution (11KB) and Sustainiac driver high-resolution (55KB) photos show the options. The SC-size drivers can be
ordered with either woodscrew mounting (for guitars having no pickguard or mounting rings) or threaded, for use on guitars with pickguards.
NOTE: The HB size driver and the SC size are IDENTICAL. The only difference is that the HB driver is mounted onto a HB-size baseplate. A plastic "dummy" cover is then attached to the driver to fill up the cavity in order to fill up the spqace.
- CONTROLS: The standard kit comes with controls for ON/OFF and Harmonic Mode. You can choose both as push-pull, or optional toggle switches for either or both controls at no extra cost. Or, choose other unusual and useful options.
Some of these involve rather exotic ideas, such as a one-lever, 5-position Superswitch control for the sustainer, or even a single lever control for both the guitar AND the Sustainiac. Visit the SUSTAINIAC CONTROLS page for a detailed look at the options.
- MOUNTING THE 9-VOLT BATTERY (There are 3 choices, or you might go for the optional ac-line powered 9-volt supply.) Go to the following page for this info: BATTERY MOUNTING AND OTHER POWER SUPPLY OPTIONS
NOT-RECOMMENDED GUITAR TYPES AND OTHER PROBLEM SETUPS:
- Any guitar with more than 24 frets: Use another guitar. The space between the bridge pickup and Sustainiac driver is quite small. This creates magnetic crosstalk between driver and bridge pickup, resulting in uncontrolled oscillation.
This means that you have to turn the sustainer gain down to stop the resulting oscillation. Sustainer performance suffers so much that you might as well not even have a sustainer. We need 3 inches MINIMUM spacing between bridge
pickup and Sustainiac driver (measured center-to-center). 3.5 inches is even better.
- Placing the driver in the middle pickup position: The problem is the space thing again, between driver and bridge pickup.
- Any guitar with a slanted neck pickup. Use another guitar. The slant will compromise the magnetic balance between the Sustainiac driver and the bridge pickup. You have to turn down the sustainer gain so much to stop the resulting oscillation
that you might as well not even have a sustainer.
- Telecasters with single-coil bridge pickup. Use another guitar. The extreme slant of the bridge pickup will compromise the magnetic balance between the Sustainiac driver and the bridge pickup. Use of the magnetic-balance tab
will not fully correct this. Harmonic mode will generally not be very good. But, Tele's with a humbucker bridge pickup works out fine, even mini-humbuckers with the slanted cavity.
- Incompatible bridge pickups: Our "bilateral" driver design works great with most common bridge pickup designs, including most active pickups (such as EMG etc.). Some bridge pickup designs are not compatible and cannot be successfully used.
Good magnetic cancellation is not possible, and sustainer performance will be compromised. Novel new pickup designs continue to be developed by clever people. Some are not compatible. This is no criticism of the quality of these pickups. It is merely a statement of
how well the Sustainiac will work with these pickup types used to furnish the input signal to the Sustainiac.
- Using the middle pickup for Sustainiac input signal, or listening to it.: The middle pickup will then provide the input signal to the sustainer (if it is blended with the bridge pickup signal). The system will oscillate (squeal). However, if you connect
the bridge pickup to the sustainer input, and listen only to the middle pickup (without blending it with the bridge pickup signal), you can listen to the middle pickup. The signal will likely have some distortion in it because of its proximity to the driver.
- Pickguards with aluminum or copper "mirror" effects, or some metallic finishes on the guitar body: Remove the foil from around the pickp area on pickguards. The magnetic pulsations from the driver induce pulsating "eddy" currents into the conductive aluminum or copper.
These in turn radiate their own magnetic pulsations. The bridge pickup responds to these magnetic pulsations. The end result is that the desired magnetic balance between driver and bridge pickup is compromised. We remove the shielding
foil that comes on US-made Strats and Jems from around the pickups. You can keep the foil over the electronics cavity. If we do your installation into a Strat, Jem, etc., then we include this service.
- Metal pickup trim rings: Mostly, these are OK. But sometimes it produces the same problem as #6. If you experience distortion or uncontrolled oscillation, try switching to a plastic trim ring. If the problem goes away, that was the reason.
- Crowded electronics cavity: Having other effects inside the electronics cavity exposes the guitar signal to more electric crosstalk from the Sustainiac circuit board and signal wires.
- Concealing the driver: If you cover up the driver (to fool people into thinking you are Superman), you move the driver farther away from the strings by the thickness of the cover. This reduces the sustainer performance. Paint should work OK. Using a metal cover
upsets the magnetic balance of the driver.
- ES335 etc. are very difficult since there is no cavity access.
- Placing a single-coil pickup next to the driver: This does not work well. The Sustainiac works fine, but the side-by-side permanent magnetic fields of our patented bilateral driver "bend" the field of a single coil pickup. The result is
that the sound of three of the strings will have about 6dB lower output level than the other three strings. Same for a humbucker with "stacked" coils. A mini-humbucker with conventional "side-by-side" coils
pickup doesn't exhibit this problem as much. In our opinion (and that of most customers), the Sustainiac driver sounds better than most mini-humbuckers. It also has the new dual-sound feature.
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.
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:
Schecter Synyster Gates Custom ® 2-humbucker guitars
Gibson/Epiphone Les Paul
"GENERIC" Semi-installations for most rear-cavity guitar types.
ABOUT YOUR GUITAR
We need to know some specific information about your guitar so we can send the proper hookup diagram and parts
with your kit.
What kind of output jack do you have (open or barrel style)? Each kit comes with a
replacement jack (stereo) that replaces your existing guitar jack, in order to activate the Sustainiac battery
when the guitar plug is inserted. To determine what style you have, Click on either picture:
Output jack choices, low resolution (10kb); Output jack choices, high resolution (70kb).
- Open-style, shown on the upper left, usually mounts to a metal plate on the side of the guitar, or a special plate
such as Stratocasters have. Open style has a visible hex-nut that is threaded onto the outside of the jack.
- Barrel-type (bottom of picture) has a flange, with no external mounting nut (mounting nut is inside the guitar body).
- 9-pin stereo jack The 9-pin jack (upper right side of picture) is a special jack, having internal switches that
connect/disconnect two or more separate batteries. If you use active electronics in the guitar (such as EMG pickups),
you need to use separate batteries, one for the EMG's, one for the Sustainiac. This requires replacing your existing guitar
jack with a special 9-pin jack.. Click on the for a PDF file which shows how the jack is
used, and why, and how it is hooked up.
We have more info on output jacks, and how they are hooked up with the Sustainiac, in our
ABOUT GUITAR CONTROLS, a PDF document.
How many pickups does your guitar have? One, two, or three. Select on ORDER FORM.
What type pickup selector does your guitar have? Select on ORDER FORM. Each drawing is based on the pickup switch type. Please know what you have before you order.
Pickup selector options
- 3-position toggle (for most 2HB guitars, Les Paul etc.)
- 3-position lever (Tele-style and some other 2-pickup guitars)
- 5-position lever (Strats, most other 3-pickup guitars, "shredders" etc.) There are 4 main styles:
- "CRL" switch. Has 8 contacts, 4 on each side of the wafer. This is the switch that Fender has used for decades. Simple, reliable, good "feel" when switching. Open construction so you can observe what is happening.
- "In-line": Has 8 contacts that are in a straight line (These switches are usually enclosed in plastic, and in our experience are generally inferior. Wimpy "feel". Consider replacing this type with the "CRL" switch that will last the life of most guitars.
- "Superswitch": Has 24 contacts, 12 contacts in a line on each of 2 sections. Has open construction so that you can see the inner workings of the switch. It is often used with coil-tapping schemes of the bridge and neck pickups, to create Strat
"quack" sounds. See picture and more info on the Controls Page.
- "VLX-91" switch used in many Ibanez guitars. Has 24 contacts, similar to Superswitch. 2 wafers, 6 contacts on each side of each wafer. See picture and more info on the Controls Page.
- Individual toggles for each pickup (some "shredders" and custom guitars).
- Some other arrangement. We need a detailed explanation, or we can't provide a useful drawing.
We have more info about pickup selectors, and how they are hooked up with the Sustainiac, in our
