Thread: Pedal Love?
Pittsburgh Modular also made a stomp-centric cab quite some time back, incorporating footswitches that could be added into your patch, etc. However, it's been quite some time since they were available new...but some poking around in the usual used device places could turn one up with a bit of diligence.
As for why it was discontinued...well, lots of itsy-bitsy knobs and jacks and wires + FEET. The problems for the avg. guitarist would be huge, especially onstage. Very much something for studio use only!
