Anyone successfully interfaced Marshall's Stompware switching riddle ? I need access to switching the verb, gate and boost at a minimum.

No midi, just the Stompware jack on the back of the amp. Are these guys using control voltage ? Help.

Do you get any switching at all?

If like my AFD100, then it's a stereo jack going into the switching port on the back... meaning I have to use a Y-split to combine two mono cables from the GCX to one stereo jack going into my amps... that goes for both my amps with switching means by jack...

JK,

Thanks for the post. Yeah I think your AFD is slightly different. Since you have two functions to switch they use a more standard TRS switch. Evidently the YJM uses the Stompware ( just standard TS cable going to a 4 function switch). My suspicion is that they are using control voltage or somehow the amp reacts to a resistance load inside the pedal and depending on that impedance it changes status on the amp. Gate on/off, Reverb on/off etc. This is all pure speculation on my part however.

Not sure. Stumped at the moment. About to perform a dissection of said YJM pedal if I can't figure this one out.

-D
