I won't be going the chip way. Got the FCB just to have it at home, but eventually I will re-sell it. Likely as soon as I get 4 button controller.

By the way, my Marshall JMP-1 came with 4 button footswitch. I have felling that it is MIDI and are just wondering...
What would happen if I cut it and install regular MIDI plug on it?
Will it work with my 11R?
Maybe it is time to visit my electronics supply store, and build conversion box instead of cutting it.

The question remains: will it work without damaging anything?

If it does, I will sell JMP with Control 8 and keep the 4 button switch for 11R.
