Yamaha MFC06 is a foot controller for Yamaha's popular FX500 multi-effects processor. It offers direct footswitch selection of up to 5 different effect programs and ON/OFF switching of the COMPRESSOR, DISTORTION, EQ, MODULATION, and REVERB stages, giving you hands-free control over your effects while performing. The MFC06 is housed in a rugged metal chassis and connects to the FX500 via a standard MIDI cable. It can be powered by either batteries or an optional AC adapter.
