MS-3 Multieffects Switcher

The MS-3 Multi Effects Switcher combines a comprehensive effects engine with a programmable loop switcher, letting you integrate Boss effects and external pedals in a unified switching system.

Built-in effects cover delay, reverb, chorus, flanger, phaser, tremolo, overdrive, distortion, compressor, EQ, and more. Three effects loops integrate external pedals into the switching system. Programmable patches store complete rig configurations including external loop assignments and internal effects settings.

Multiple footswitches for patch selection and individual effect toggling. MIDI in/out for external control. Expression pedal input. The three effects loops can route external pedals in any order within the signal chain.

The MS-3 solves a specific problem: integrating favorite external pedals with built-in effects under unified switching control. For players who want their boutique drive pedals alongside Boss modulation and delay, all switchable from a single system.
