MLC Mark L Custom FX25 & 2nd Expander Midi Switcher, remote power

This listing is for an elite, touring-grade Mark L Custom FX25 MKII MIDI Foot Controller system paired with the matching 2nd Expander. Built by MLC in Poland, this boutique system provides world-class switching capabilities for high-end guitar racks, Fractal Audio, Kemper, and other modern digital modeller configurations.

This comprehensive bundle features the heavy-duty Remote Power/MIDI Rack Link Interface box, allowing you to keep all power bricks and messy data connections away from the floor.No issues, runs well, incredible amount of flexibility - I've used it with a ton of midi controlled pedals, as well as rack mounted switchers and Fractal FM3/FM9.

It's incredibly easy to program on the unit, or to use the included software. Unit is as pictured - in incredible shape for 14 years old, but has scrapes and scratches from use - I can provide more pictures if required.
