Despite the name this is based on the MK1 tonebender. It's less fussy about where in the chain it goes and has silicon transistors for stability. It's a great sounding fuzz that stacks surprisingly well into a dirty amp. Being a tone bender it doesn't clean up as well as a fuzz face when you turn down the volume knob kn your guitar but it provides lots of different levels of fuzzy drive. Great sounding and versatile Tonebender at a decent price.
