Suggestions from the massive on a boost- not distortion/not "tube emulator"/fuzz/ad nasuem pedal..I want to give my envelope filter a bit more juice, upper harmonic wise.. I tried a few lo ball things the dod Monkey brains or whatever it's called..an 808 sim..nope..the variety of Boss crap..nope.. I am thinking maybe a dod 250..or? anyone here doing this? a simple clean boost works wonders before your filter..but which one?
