The preamp circuitboard is installed on the guitar-bottom with Velcro. It measures only 2.5″ x 2.75″. The circuit board has a metal shield/backing but it is fully open to the top to allow for adjusting the EQ trimmers. It is designed to be preset to perfectly balance the pickup and mic in your guitar. It offers powerful +/- 20 dB EQ without the necessity to cut a hole in your valuable instrument. You can place it either directly under the soundhole for easy access with a long, small-blade flathead screwdriver or you can hide it deeper in your guitar. This system does not require any destructive alteration of your guitar other than the installation of the endpin jack.
