The Earthquaker Devices Bellows is a transistor based overdrive to fuzz pedal that gets by with only two knobs - delivering a lot of character!
One great thing about the Bellows is, that it works great with both electric bass and electric guitars. Whatever you plug into it, it will drive - actually, it will fuzz, too. On low drive settings the Bellows is a mild fellow, the easy to handle type. However, turning the drive knob to full will result in a full range fuzz straight out of fuzz land.
To sum it up, the Earthquaker Devices Bellows is an extremely useful gain pedal that can drive an entire show, from the subtle first song to the shredding finale.
