Boffin FX Electric Guitar Onboard Toggle Switch Boost Preamp Upgrade

The Toggle Switch Boost provides gain at your fingertips. No need to switch on an effects pedal or turn on the dirty channel of an amplifier. It’s all on the guitar.

The Toggle Switch Boost is powered by a MOSFET circuit to provide powerful gain up to 20 dB efficiently with a 9V battery.

Adjusting the Toggle SwitchBoost is handled by a trimpot located on the board. Turning the trimpot clockwise increases the amount of boost.
