sustainers for stringed musical instruments



We have used Auxilliary ("Aux") circuit boards for years for our guitar manufacturer customers such as Schecter and Ibanez. These boards hold the Sustainiac controls. The Aux boards connect to our main circuit boards by pre-wired harnesses. This eliminates much installation labor. It also makes the end product more consistent, and greatly reduces the chance that uncontrolled squealing (oscillation) or "grunge" in the guitar signal due to crosstalk from certain Sustainiac wires to the guitar signal wires. In fact we think this will make the typical Sustainiac installation so much easier and less expensive for our customers that this will become the most popular installation option. Scroll down to see the photos below.

We have decided to make this an option in order to reduce the complexity of installing the Sustainiac, and also to reduce the chance of installation errors which sometimes causes frustration with customers and even skilled technicians. As our company Maniac Music Inc. grows with the increasing popularity of the Sustainiac, we have less and less time to answer hundreds of customer calls for help with their Sustainiac installations. Our new "Aux-TT" board with toggle controls sits vertically in the control cavity as shown in the photo of a Jackson DK-2 guitar cavity below. It needs 1.35 inches (35mm) of cavity depth. Or, you can eaily modify the cavity depth as shown with the Jackson DK-2 installation below. The new (May 2018) optional Aux boards (Aux-TT, Aux-JS, Aux-2) each add $10 to the Stealth PRO kit price IF you order one INSTEAD of the normal controls and wire harness. Add $20.00 if you want BOTH the Aux board AND normal controls.

This is a good $20 option for end users to save much time and potential frustration by greatly simplifying the Sustainiac installation. The Aux-TT board is 1.8 in. (46mm) wide x 1.35 in. (35mm) tall. (Requires 1.35 in. (35mm) cavity depth)

Jackson DK-2 guitar cavity prep for Aux-TT board, Using a Forstner bit (shown at left in photo) and chisel to make the cavity wall thinner in the switch region. Forstner bits are very easy to control and make a neat cut.

Sustainiac Aux-JS board. This board is installed into all the Ibanez JS2480 guitars. It is a good $20.00 option for end users to install into their own JS model guitar. It has a toggle switch for Sustainiac Harmonic Mode, and push-pull tone control for ON/OFF. A tone capacitor is mounted to the board. The Aux-JS board is 2.2 in. (56mm) wide x 1.35 in. (35mm) tall. (Requires 1.35 in. (35mm) cavity depth)

Sustainiac Aux-2 board The Aux 2 board is mounted horizontally to the cavity wall. It takes up more room in the cavity than our Aux-TT board. It has been used for years in various Schecter models but we offer it for guitars with roomier cavities.
