Whirlwind MultiSelector PRO 4-to-1 Instrument Switcher

The MultiSelector PRO is a unidirectional 4-to-1 instrument switcher: four instruments in, one amplifier or signal chain out. Unidirectional means it is built for that direction rather than being a general purpose patch, which is what lets the switching be clean.

It is controlled from the MultiSelector Remote footswitch, part number MLTSELPRO4XR, which connects over an ordinary three-pin XLR mic cable and is sold separately.
