is it a KILLER sounding fuzz! Had a chance to play with one all day on Sat and it was a blast. I have had muffs over the years but none that have sounded this good, touch sensitive, or cleaned up this well! For my tastes it had the perfect amount of gain.. I find that high gain muffs get lost in the mix within my band but this had just enough bite to it... and the gritty sounds you could pull off.. Just a shockingly good pedal.
