I'm using this pedal with a Les Paul plugged in to an Egnator amp. I get a super chunky, crunchy sound that is making me want to give up on the rest of my pedsls and use this setup exclusively. With the coils split I get a nice Brian May sound and with the humbucker in the bridge position get a great Tommy Iommi sound. It is definitely a noisy pedal, so be prepared for that. Treble boosters always are, even Brian May said so.
