The Sustainiac® Stealth PRO sustain system drives the strings of an electric guitar into infinite feedback sustain of string vibrations by electromagnetic feedback.

Professional installation is recommended. We offer full installation and repair services in our shop in Los Angeles, accepting guitar shipments from all over North America. Please send us an email if you'd like to arrange an installation.

The Sustainiac® Stealth PRO contains the following features:

SUSTAINIAC DRIVER: The Sustainiac driver pickup replaces your neck pickup, it works as a regular pickup when sustainer is off. It's available in black or white, and in the following options:

● Humbucker

● Threaded Single (For Strat or pickguard)

● Direct-Mount Single (For mounting directly onto the guitar's body)

● 7 string Humbucker (Only available in Black)

The humbucker size driver is 84mm x 35mm x 22mm.

The single size driver is 84mm x 18mm x 22mm.

A threaded pickup is to be mounted onto a pickguard or pickup ring.

A direct-mount (or wood-mount) is mounted or screwed directly onto the guitar's body.

SUSTAINIAC MAIN CIRCUIT BOARD: The Sustainiac circuit board can be installed into most electric guitar electronics cavities with little or no routing. Measures 90mm x 30mm (without connectors).

There are 5 different types of main boards, depending on your bridge pickup type:

● Main Board for Passive humbucker (Such as Seymour Duncan JB - Most common)

● Main Board for Passive single coil or P-90

● Main Board for Active EMG

● Main Board for Active Fishman

● Main Board for Bass

In most configurations, the Stealth Pro has an ON/OFF control switch and also a 3-position MODE control switch (standard, mix and harmonic modes).

We offer 3 types of Auxiliary control boards:

The Aux-TT board (most popular) is 1.8 in. (46mm) wide x 1.8 in. (30mm) tall. (Requires 1.35 in. (35mm) cavity depth). The two toggle switches are spaced 1.00 inches (25.4mm) apart.

The AUX-RG board is the smallest Sustainiac switch board, to be positioned horizontally, while other Aux boards are placed vertically. Measures 40mm by 25mm. About 1 inch of depth is needed inside the cavity.

The AUX-JS board (Joe Satriani signature) has a sustain ON/OFF push/pull pot (also works as your tone pot) and a sustain MODE toggle switch. Measures 55m x 35mm.

Auxiliary boards are not required, you can use loose toggle switches, or push/pull pots for turning sustain On and Off, and to switch between modes.

Operation of Push/Pull pots:

Pot 1 (Volume):
● Pushed in: Sustain Off.
● Pulled out: Sustain On

Pot 2 (Mode Selector):

● Pushed in, knob rotated full clockwise = Normal mode.
● Pushed in, knob rotated full counter-clockwise = Harmonic mode.
● Pulled out, knob rotated full clockwise = Mix mode.
● Pulled out, knob rotated full counter-clockwise = Harmonic mode (with a few harmonics being different than pushed in).

OEM Board

The OEM boards have been used for over 20 years by guitar manufacturers such as Jackson and Schecter. These boards are electrically identical to the retrofit boards found in the standard kits. The OEM board has been widened to allow the Sustainiac toggle switches to be mounted directly to the board. Removing the need for any soldering. 

The main advantage of this form of installation is that the hookup is far easier. It also eliminates the issue of incorrect wire placement within the control cavity which can cause electrical crosstalk and squealing.

Much like the AUX boards, also offered by Sustainiac, the number of soldering connections is about half that of a traditional installation. 

But there is always a compromise. The OEM board is normally too big for most guitar control cavities. This means that either a large addition needs to be made to the original cavity or a separate Sustainiac cavity needs to be routed to position the toggle switches in the optimum position.

The OEM board is also designed for guitars with a Humbucker bridge pickup.

Due to the shape and toggle position on the board, it is highly advisable that these OEM boards are used for flat-topped bodies. An installation on a guitar with a contoured top would be very hard to achieve. In these cases, a retrofit board install is advised.

With the toggle switch mounted directly to the board, it also means that these kits are ‘toggle switch only’. There is no Push/Pull pot install option with the OEM boards.

With the popularity of the Sustainiac Stealth PRO system increasing each year, Sustainiac are now releasing these OEM boards for sale.

These OEM boards are really aimed more at the custom guitar maker rather than someone who wants to drop a Sustainiac Stealth Pro kit into an existing guitar. Adding a cavity suitable for the OEM board at the design phase is far simpler than having to retrofit a board of this size into a guitar. Having said that, it’s totally possible!
