Boosting this with an MXR Distortion + and getting some amazing thick 90's fuzztones, don't forget to play around with your guitars tone knob for even more girth.
Solid build, pretty much what you can expect from EHX, knobs work as they should, tone bypass switch gives some interesting sounds, but the main attraction can most likely be found between 10:30 and 1 o' clock ;)
Sounds fantastic through my bass amp (while using my standard guitar, haven't really tried on bass), especially with some of the mids cut out on the graphic EQ.
