Hi there,

I am a new owner of a QC and I feel a bit lost regarding expression pedal. I have a Dunlop DVP5 but it doesn’t seems to work. I found no signal in my QC

I have read that I need to use a special cable. Do I just need a TRS patch cable like this ? Or do I need to plug something else in the other input of the pedal ?

Thanks a lot !

William

Yes that’s the cable you need. I have that same expression pedal and am very happy with it.

here’s a decent video tutorial. You should calibrate first, then assign the XP where you want it.
