Mad Professor pedals are pretty well known and loved by the guitarists in 30s/40s age bracket.
mostly more blues/jazz based guys, alternative rock, etc.
the CLIFFHANGER II is one of the BEST high gain distortion pedals I have ever heard IN MY LIFE, and also sounds GREAT with downtuned styles, probably would rip with 7 string guitars, and could be a BREAKTHRU pedal to get the attention of the younger players in their 20s.
just a suggestion.....i know the CH II is still a research pedal. But I think Mad Professor line NEEDS a super high gain pedal that is not the MRD - 80s based rock -- but something MODERN........and the CH II is the ONE
