K&K Onboard Trinity Active Dual-Source Pickup System with Internal Preamp
From the K&K website:
"The Onboard Trinity System is a dual-source pickup and internal mic system with an onboard preamp.
The system comes completely assembled with TRSS stereo endpin-jack wired in mono so a standard guitar cable can be used. No soldering is necessary. A velcro mounted battery holder and a velcro mounted dual volume control unit are also included. Individual thumbwheel-pots for the mic and pickup are mounted inside the edge of the soundhole.
Installing the Trinity System:
The preamp circuit board is installed inside the guitar 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 adjustment of 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 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."
