The Marshall MPM4e is an optional 4-way footswitch for the JMP-1, which provides a simple means of selecting 4 patches. The footswitch will call up patches 1 to 4, however, and the Mapping facility can be used to call up any 4 of the 100 JMP-1 patches.
This footswitch is brand new, in box from in stock at Mall Music Sydney.
