Hahaha...I use MT2...the pedal that the world has forsaken :smt109
Though I use it as a boost for my solos...as for the settings, it really depends on the amp and other pedals you're using it with. I go easy on the 'highs'...I guess the key is the mid freq...
Like the often-used quote..."Tone is in the hands"...so, don't be surprised if the artiste(s)/guitarist(s) you are really impressed with happen(s) to use a MT2 in their setup... :wink:
Bottom line is: what works for me might not be for you, and vice versa...so, just experiment and let your ears be the judge
