OK, has anyone ever thought of, or hopefully even tried this:
What I am imagining is a simple way to turn this 2 channel amp into a 3 channel amp (sort of).
I would like to add a footswitch-selectable second saturation pot on the overdrive channel so that two levels of saturation could be selected from a foot switch.
Clean channel - operates normally in every way
Overdrive channel - with the footswitch in one position the level of saturation is determined by the position of the factory saturation pot, when the footswitch is in the other position, an alternate level of saturation is determined by selecting a second, newly installed pot which would function exactly as the original saturation pot did, you can just choose which one to use at any given time.
I would actually be willing to give up use of the mute function of the 2 button footswitch to streamline this further.
This doesn't really make it a 3 channel amp, but to my ears the overdrive channel sounded great on the same EQ settings I used with both minimum and maximum saturation settings.
Now, tell me all the reasons this can't be done.....
