There's nothing like a good C4 preset that sounds just like a classic synth.  Mark Neary has captured the 80s synth bass-style sound as performed by Bob Christianson on Chaka Khan's hit "What Cha Gonna Do For Me".  He gets razor-close with our pedal, utilizing a sine + saw wave combo, some mild distortion, and a 2-pole lowpass filter on the sine oscillator.  Hear it for yourself!  @markneary1, thanks for putting this video together.  Sounds great in a studio mix!
