BOSS MS-3 Multi Effects Switcher (MS-3)

The BOSS MS-3 Multi Effects Switcher is a compact pedalboard control system that combines a powerful multi-effects processor with three external effects loops. Designed for guitarists and bassists who want a professional setup without a large pedalboard, the MS-3 can run six internal effects simultaneously while integrating up to three external stompboxes.

Beyond effects processing, the MS-3 serves as the central control hub for a complete guitar or bass rig. It can switch amplifier channels, control compatible effects, communicate with MIDI equipment, and provide extensive real-time control through its footswitches, external controllers, and expression pedals.
