Arrived yesterday. I ordered it particularly to use with a Gretsch with no real tone controls. The guitar has individual pickup volumes, and a master volume, but the only EQ is the 'mud switch' which gives you the choice between no, a little, and a lot of treble cut. My amps have limited EQ options as well, so I decided I needed to invest in a pedal. I have to say it's everything I hoped for and more (a lot of clean boost to it). I don't really know what else to say about an EQ pedal, but when I searched for this particular pedal before I bought it, I didn't find much here, so I figured I'd start a thread to let other potential buyers know that one person at least thinks it's a very quality pedal.
