Did you hear my demo on the zero through flanger with expression pedal? This pedal is more geared towards studio grade modulation such as Leslie, Vibrato, Tremolo, Chorus, Vibrato, Wah using the expression pedal and all of the patches can incorporate wah tones but it's not really designed to be one of those EHX or ZVex wacky type sounding pedals that chop up or morph the sounds etc. while they all have their place and purpose the MF is definitely not one of those though I'm sure with enough knob twisting you could come up with something way out as I did with the negative zero through flanger setting.
