channel switchg with gt3 without expensive midi controller

[sander78]

I thought of two ideas to switch channels with an gt3 and a caliber.50 and was wondering if someones tried it already. I hate to pay 300 euro more to get a gt8 only for the channel switch function I want to know if someone's tried it allready.

One idea is this: the mesa has one gain for 2 channels thus either a perfect clean and a less nice distortion or visa versa. The switching is controlled by a footswitch but if one could do this with a gt that has not the channel switch mode like a gt8 then prob. you could use the stereo output is my idea.

With the footcontrolled the signal goes either to channel one or two. What if you'd make two jack input connectors?
So one jack input is connected to channel 1 and the other (the new one) to channel 2. I guess you could find these paths in the amplifier right after the jack input connector because it routes the incomming signal to either1 or 2.

Then use two cables for each channel going to L or R on the gt. Then program for each patch the channel (L or R: hence clean or distortion) u use.

The only concerns I have is:
1)what happens if both L and R are activated at the same time. 2) what if u play for example on the clean channel e.g. "L" and "r" is not grounded in the gt internal connections. Then perhaps it will pickup some noise which will be amplified by the distorted chanel.


Another idea is that if you program a midi comand, no matter which one I guess, then for a sec or so a signal is put on the midi output connector. U could use this to activate a relais switch (perhaps some circuit to prevent to high current and blowing up the output).
Now, if the gt hase a command that stays high:for example it stays + 5v or so then it’s easy. But if it is just a sec and goes back to “0” again. Then I guess one should use some logics like a flipflop are PIC controller or so.

Did some one tried one of this methods allready? What were you’re findings?
