Voodoo Lab

I set up my gcx and gcp yesterday, everything works great except the amp channel switching. The 3ch Smallbox comes with a 2 switch pedal. 1 switch changes from ch1 to CH2, the 2nd switch activates ch3.

The cable I’m using is a Y cable, TRS x TSxTS. TRS in amp channel selector, I’m using loop 1 and 2 on the gcx.

I’m getting ch1 and ch3 but not ch2

On the gcp, it’s set to normal.
I’m sure this is an easy fix but I’m not sure where to start.
Thanks

I figured it out. With no switches pushed on the gcp, it’s on ch 2. It took me awhile to realize that. Everything works awesome now.
