Moog Music Forum

So I'm looking at building a DIY expression pedal for a moog mf drive, I was wondering if anyone had any experience doing this? Alternatively if anyone has found a schematic for a moog expression pedal that I could copy? or knows of another brand of expression pedal that works with mf pedals?
My first attempt used a 100k linear taper pot salvaged from a vox wah, it had some effect but the sweep was limited to the bottom half of the pot's range so any help would be much appreciated before I start randomly buying different pots from the internet ))

Hello girafffe, welcome to the forum!

I’m sure you can find schematics of the Moog EP online… or any other expression pedal -no offense meant
In addition to the main potentiometer (the one activated by the pedal itself), you may want to implement a way to select the polarity (at least at first for testing) and one/two others potentiometers for setting the low and high levels.. for a deluxe expression pedal version.

Show us what you come with!

cheers for the response man, it seems last time I researched this I did a pretty sub par job, I've found some more info and I'll try switching the polarity to see what I come up with !
