This is a great EQ pedal endorsed by Paul Gilbert. It can be used as a nice boost but was designed as an "unboost" actually. It's very effective at cleaning up a crunchy distorted tube amp. Basically simulates rolling back your guitar volume but you can tailor the tone for brighter, darker etc. It was $130 new so i'm wanting $90 shipped in north america. Or trade for a Duncan Phat Cat!
