I need to confirm or debunk -- Is an expression pedal generally a potentiometer? If not, I'll have to re-think this.
But if so, how would a Moog EP3 correspond with this TRS Jack: http://smallbear-electronics.mybigcomme ... -pc-mount/
Lug '1' is near the 'jackhole'. '2' and '3' are the 'away' lugs. I would think that '1' would correspond with the EXP pedal's 'wiper'? .. and '2' and '3' would be CW/CCW?
...Or maybe '1' is intended to be CW, and '2' is Wiper, and '3' is CCW?
TIA

so i hooked this jack up to its EP3 pedal, and then the lugs to a DMM set to 200k, and ranged between '50' and '100' between lugs 1 and 2, then '0' to '50' between lugs 3 and 1, then a full range of 0-100 between lugs 2 and 3. ...interesting.
1-2 ... 50-100
1-3.... 0-50
2-3... 0-100
but then i tried a regular 'B100k' pot, and got results more along the lines of what i'd originally expected... Wiper to either CW or CCW goes from 0-100, CW-CCW basically remains at 100....
anyway, i was trying to put an exp jack into a fuzz circuit to work with the EP3, in order to have a simple lowpass filter...

ok... finally (maybe) getting somewhere with understanding this... : http://www.strymon.net/strymon-tech-cor ... ion-pedal/
(ooh... on the breadboard, just got a passive filter to work with exp... and no loss/gain in volume when exp unplugged... ay yai yai)

ok, so i was trying to build a filter into a fuzz pedal, and have the filter be exp-able. i've got a working model on a breadboard.
apologies for any 'idiotic' questions posed here whilst trying to figure out electronics.
there's still a ton to learn, but this electronics stuff is fun!
