Ground Stereo Pre

Working closely with bass legend Alain Caron, we have designed a stereo preamp that is innovative, useful, and truly unique in the market. It’s a foot pedal preamp—giving you convenient access to your controls at the front of the stage along with your effect pedals. Use the headphone output for private practicing, and connect an iPod or MP3 player to the aux input for playing along. Although it can be used mono, the Ground Stereo Pre is designed to be used in stereo with two powered cabinets, and stereo effects.
