This is a clone pedal of the popular Tommy's Effects. Please take a close look at the photos, as there are some scratches. I like it, so I may cancel the listing depending on how I organize my other equipment. I really like the rough distortion. With a single-coil pickup, it sounds great, like John Frusciante's tone from 2007. Please also check the contents of the instruction manual from the images. The following is a quote: This overdrive allows for a wide range of sound creation by mixing two gain knobs: one (top left) that boosts high frequencies and one (top right) that boosts all frequencies. The image I had in mind was using it like linking the high treble and normal channels of an old Marshall. (This does not mean it produces the same sound) The distortion is created using a discrete (MOSFET only) method, which allows for a good distortion even with a bridge humbucker, and by lowering the gain, it can also sound good with a single-coil neck pickup. Furthermore, since there is also a booster channel in addition to the distortion channel, you can get even deeper distortion by boosting it in the previous stage. The original is the ZVEX Box of Rock.
