Hello. Everyone. I was wondering if anyone with technical knowledge could help me out. It’s my understanding that both pots in the EP2 are 100k pots. What then is the impedance of the pedal with the attenuator trim pot set halfway up?
Could I then put this value of a pot inside of an ernie ball volume pedal to give the same range of control when hooked up to a moogerfooger as an EP2 does with its attenuator trim pot set halfway up?
Thanks
I use my ernie ball volume pedal as an expression pedal on occasion by using either an insert cable or by plugging the input half way into a second cv in. I find it more useful as a cv attenuator though, patching a cv through it. The volume pedal has a log pot, while the ep 2 has a linear pot. To get the trim pot function just wire the second pot to the output of the first one. The first pot (the one connected to the pedal) should have one of the outer lugs connected to ring of the trs plug, the other outer lug connected to ground, the sleeve, and the middle lug to the one of the outer lugs of the second pot, the other outer lug of that pot to ground, then the middle lug to of that pot the tip of the plug. The value of the pot is not very important because it is just being used as a voltage divider, but it should be linear. If you still want to maintain volume pedal function then instead of connecting the stuff to a plug replace tip with output and sleeve with input. Using the jacks is probably better because then you can use it to attenuate cv instead of just expression. Also I don’t have a ep2, so they may have done it different (switching the pots) but I think this should work. If the something works backwards, either the pedal or the trim, then switch the outer lugs.
