The Fuller Drive is a FET driven overdrive to make your amp sound like a cranked vintage British amp. From very low gain (almost clean) to cranked overdrive. A very natural and touch-sensitive pedal, which cleans up when you turn your guitar volume down. Works great with any guitar and amplifier. If you’re playing in a small venue and you’re not able to crank up your amp, this is the pedal to go. Opens up and widens your sound.
