Installation Tips
Many guitar cavities are coated with either electrically conductive paints or
foil tapes to help isolate the circuitry from interference. When installing the
Acousti-Phonic Intelligent Pre-amp it is very important to make sure that the
pre-amp is completely isolated from this electrically conductive material.
Do not attempt to install the pre-amp by using screws through the two holes in
the pre-amp, as they are there only for manufacturing purposes. Double sided
adhesive tape or hot glue should be used.
Make sure that all plug-in connections are properly in place.
If you are using a wireless system for the Acousti-Phonic Pre-amp sound
you need to have your control cavity well shielded with foil tape to stop RF
interference.
