Overdrive effect pedal for electric bass guitar that is able to tweak the EQ and crunch to where it can add a warm ‘tube’ sound to modern digital bass amps and actually improve their performance. It creates that famous John Entwhistle (The Who) tone, big, round and phat with just the right amount of sustain to place the bass properly in the mix and allow it to ‘pop’ in live and recording situations. The Drive control blends evenly with the bass tones, rather than sitting on top like so many others, and very naturally maintains a full bottom-end. Gain, Bass-Mid-Treble, Level Controls look after the sound, and the regulated and switch-able power supply (115-240V) provides the pedal with tons of headroom.
