I've just purchased a BOSS GT 100 and am using it with a Blackstar HT Club 40 combo amp. I'm using the four cable method for connections. I am also using a Blackstar foot switch with a channel switch and reverb switch. This is plugged into the back of the Blackstar. I have a question. How can I switch between the GT100 preamps and the Blackstar preamp with just a push of a switch or pedal? I can do it manually by turning on the S/R and turning off the GT100 preamps in the effects screen of the pedal. But, I can't do it with just a push of a button. I know it can be done, but how? Any ideas?

I just added a BOSS FS 6 to the Sub CTL/EXP Jack. I don't know what to do with it:)
