Sustainiac® KFK Kit

Full Sustainiac® kit including an active EMG 81 humbucker for bridge position, and the EMG PA2 preamp booster, as used by Kerry King.

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 (Tone):

● 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).
