My blackstar stock channel switching pedal is not working while using hx effects. I cannot switch to channel two. It's as if channel two is bypassed. The pedal turns red as does the channel two light but channel two seems to be disabled. If I plug my guitar directly into my amp and disconnect the hx effects entirely channel two works again, but once I reconnect the hx effects the stock pedal can only be used to turn on and off reverb and channel switching is disabled. I'm currently using the 4 cable method.
