The Sustainiac Aux-TT board connects to the main circuit boards by pre-wired harnesses. This eliminates much installation labour. 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 for customers that this will become the most popular installation option.
The Aux-TT board with it’s two toggle controls (that’s where the TT comes from) sits vertically in the control cavity. It needs at least 1.35 inches (35mm) of cavity depth.
The Aux-TT board dimension are:
1.8 in. (46mm) wide x 1.35 in. (35mm) tall. The board requires a 1.35 in (35mm) cavity depth. But depending on the mounting surface thickness, you may need as much as 1.57 in. (40mm) clearance.
The two toggle switches are spaced 1.00 inches (25.4mm) apart and require a 0.28 in. (7mm) hole.
