I wonder if this amp can be modded such that the one of the footswitch buttons also switches on Mid-Boost (in addition to activating preamp bypass PAB).

Clean channel: sounds lovely without mid-boost / PAB.

OD channel: sounds heavenly with both mid-boost and PAB activated.

I would therefore want the PAB button on the footswitch to simultaneously activate Mid-Boost and PAB.

Another option might be to use a 3 button footswitch (separate buttons for Clean/OD, PAB and Mid-Boost). But how would I wire the amp please?

Expert opinions gratefully appreciated...
