I've decided that I need to expand my setup, as far as switching and effects go, so I've decided to grab a G-major and Behringer FCB1010 to control it with.

Now, I know the G-major can be setup to change my amps channels via a TRS jack (on footswitch, one button is for FX loop on/off, one for channel switching), but I have a dilemma and a possible solution. I just need to run it by some experts to make sure it'll work in practice, not just theory.

I always run an OD pedal for my distorted sounds, and turn it off on cleans. Now, I could spend 200 dollars on a dedicated midi loop to have the G-Major control it and assign it to the patches needed, but I don't have that kind of money. I don't want to have the OD pedal infront of me for reasons of cable clutter and powering the thing, as well as tapdancing to switch between cleans/distortion.

Now, the switch on my OD pedal has three wires going to it, so I assume I could replace it with a TRS jack and be able to externally control it (via.. G-major for instance). The G-major only has one TRS control out, though. What I want to do is wire up the pedal to have that TRS jack, run a TRS Y cable from the control jack of the G-major and have one end go to the OD, one to the amp. What I'm trying to do is have the OD switched on and off automatically when I change channels.

The only problem I can think of is that the way the jacks would be wired up might cause the cleans to have the OD pedal on and the distortion to have it off (AKA Backwards to what I want), but I believe this could be remedied by switching a wire or two?

Anyways, let me know if this would actually work, or if any of you have tried it.

The FCB1010 also has two jacks for switching amp channels, so you could use one jack for the amp footswitch and the other for the distortion pedal.

I don’t think the circuit will work as you described it.
The TRS connection just provides a closed contact for switching logic while the switch for the OD pedal routes the audio signal.

You could however, route the wires from the OD switch though a small relay, connect one end of the relay coil to the pedal supply, and use the TRS connection to make / break the relay coil return (ground).

In this case, I'd just be running it into the control jack of the G Major.At worst, I can run forsaid cable out to the FCB1010 and program the OD pedal in afterwards. I didn't know it had those relay jacks, thanks!

The TRS may not be providing a quot;dryquot; set of switching contacts. More likely it is simply changing logic states to from high to low. (grounding your audio signal when active).

Ah ok I see what you're saying now. I'll have to try it out when I get it... At worst, I'll have to save up for one of those midi relay's or make my own.
