EHX Small Clone - Volume Mod

HeikoAbendroth · Post by **HeikoAbendroth** » 25 Apr 2012, 14:59

A musician has asked me to increase the output level of the chorus a little bit.

To do this, search for resistance R19 (10 k) and shrunk it down to desire (smaller = more output level)

I decided to solder a trimm pot (25K) on the back side of the pcb parallel to the existing R19, now you can set the output for your choice.

A relatively simple modification - have fun.

There is more than one 10K resistor in the circuit. Would 10k be close to 20k and 22k?

R19 is the one, (10k) it connects to pin 6 of the 4558.

Could i replace the r10k by a 20K trimpot and an external potentiometer for volume control?

The Jeds Peds PCB Small Clone brings to an external volume control, with a different approach. My question is that there are many other components with different values. Would the only change to volume control be replacing the 33K resistor with a potentiometer or do any other changes need to be made?
