Function switch control setup on AC30 and fender twin

[Ikslopot]

Hello. What is the recommended setup for the function switch control outs on the PBC10 going to a 2003 Vox AC30 handwired w reverb and tremolo and a blackfaced 71 Fender Twin with beautiful reverb and vibrato/trem?

The back of my fender has what looks like an stereo RCA split to mono. If I used a quarter inch to 3.5mm adapter and applied it to the stereo side of the RCA cable and plugged it into the PCB10 FN1 and FN2 would it work?

Thinks are working with the Vox and I am able to turn Trem and reverb on and off. The light indicator was showing off when it was on on reverb. I inversed that and now when it is on the light indicates on.

Thanks RJM!!!!

Sounds like you have the Vox switching taken care of, great!

I'd be careful with the Fender though. You should try to get as much information as you can about it's remote/foot-switch jack. User manual might indicate some details but a schematic would be better in this case. On some amps, Fender implements proprietary switching via different voltages and such. Sometimes simple relay contacts opening and closing aren't enough, and some extra parts such as diodes are necessary.

Thanks for the response, Mario! You are awesome.

I checked the manual. That didn’t tell me anything useful at all.

I ordered a TRS to RCA mono outs. If I try this is there any risk of damaging anything or is the worse that could happen is that it just won’t work?

I reached out to my amp tech. I bet he will know.

Well, I was able to turn the vibrato off and on with the PCB via a 1/4 inch trs out to a RCA mono split; however, the reverb side has a metal ground (?not sure?) soldered to the side in the above image. That leads to the interior of the remote footswitch here.

The normal RCA even getting close without touching made a noise. Not trying that. Not sure what is up with that. It may be hot? I am not sure.

I am happy to turn vibrato on and off.

If anyone can explain the reverb and my options there I appreciate it. I know how to solder and such. I’ll work it out somehow. If someone knows the next move though please share. Thanks.
