Location
Before you cut the cavity on the side of the guitar,choose a compatible location:• Pick a location that allows the preamp
to swing freely without bumping into theinternal braces. The preamp housing
requires at least 111⁄16” (4.3cm)
clearance inside the guitar.
• Position the preamp on the flattest convenient surface on the side of the instrument.
The flattest and most comfortable location is usuallyat the upper bout, just above the instrument’s waist
and well below the shoulder (figure 1). Note thatwhen the bezel is fastened to the side, it will bend
just enough to conform to the curves of moststandard instruments.

To help prevent cracks and provide structural
support for the preamp, we recommend reinforcing
the mounting area with thin veneer before you cut
out the cavity.

Installation
1. Once you select the mounting location, affix
the template and cut out the cavity. Use a #45(.082”, 2mm) drill for the screw holes.
2. Install the endpin jack per Switchjack Installation
Instructions.
3. To access the input, open the trap door on theback of the preamp chassis (figures 2, 3).

4. Fasten the pickup wires to the terminal block(figure 4). The signal wire goes to the terminal
marked “IN” and the shield wire goes to the “GND.”
Tighten the screws on the block to secure the wires.

Sound Image upload
Install the included Aura Image Gallery software on
your computer. Open the preamp compartment andconnect a “mini-B” USB cable between the preampand the computer (figure 6). Follow the onscreen
