Hi - I Have recently got a HX Effects and cabled it up via the 4CM. I am getting sound but I have a Marshall TSL with 3 channels. When I change the channels on the amp (using a marshall footswitch), the sound doesn't change. Its as its just going through the HX and not reflecting if I change the Amp channel form say clean to crunch. I suspect its something to do do with signal path but not sure where to start.
I feel like such a newbie wit this stuff so apologies if dumbarse post. Any obvious errors?
Thanks
