This pedal is great! There is so much drive available on tap it's scary. I love the classic Ibanez look and the white LED is spellbinding! The pedal is usable for bass in "turbo" mode only - although Mr. Keeley offered to mod it for more low end in the other three modes for free - but it does everything i could ever want in that mode. The pedal can go from warm, overdrive to all out distortion. Tone control is not as flexible as I would like but still very usable. Plus, Robert Keeley is an incredibly nice guy to work with. When he found out that the other modes did not have as much bass as the turbo mode, he offered to mod it for free with return shipping included!
