Voodoo Lab

I am experiencing random volume drops while playing. The "active" light on my GCX blinks in synch with the volume drops? Could this be an issue with my GCX, or do you think its a bad cable somewhere in the signal?

My Signal chain is:

Guitar
GCX (which is switching channels on my Engl Savage 120, and switching G-Major patches)
ISP Decimator pro Rack G
G-Major
Engl Savage 120



Thanks in advance,
Mike

Are you using the Expression Pedal ports?

If not, check that both ports are turned off in the Pedals menu under Setup Mode.


Do you have anything connected to the Ground Control Pro MIDI In jack?
