How are you trying to change Legacy channels, via the GCPro or via the G-Major Relays?

I merged the two threads so they are all together ;)

From your other thread I see you also have the GCX... are GCX any loops connected to the 1/4" Reverb Footswitch Jack on the back of the amp? If so, its probably best to disconnect this.

Also, exactly which model of Legacy amp is this?

OK, so the original Legacy amp used a TRS jack for the footswitch. To correctly control the footswitch functions you will need an Insert Point Cable. This is like a Y cable but it has a single TRS (stereo) end that breaks out to two TS (mono) ends, sometimes labeled "Tip" and "Ring". The TS ends will connect to the OUT/N.O. jacks of two GCX Loops (one to control the Channel A/B and the other to control the Reverb On/Off). The TRS end will connect to the amp's footswitch jack.

Here is a diagram that is quite similar to your setup with four pedals routed to the front of the amp using Loops 1-4, and has loops 7 & 8 controlling the footswitch functions using an Insert Point Cable.

Also, the original Legacy (models VL100/VL212) manual states the following about the footswitch jack...
Most foot pedals with 2 switches, a stereo cord and plug will work. First, the channel SELECT switch on the front panel must be selected to the “OUT” (channel 1) position before the footswitch will work. Now that you are connected correctly, the channels and reverb can be switched remotely.
Note: If a hum is heard in the speakers, the select switch is in the wrong position (this will not harm the amp).


Let us know how it goes!
