BOSS Multi Effects Switcher with Three Loops, Complete Foot Control, USB, and Remote Editing

The BOSS MS-3 Multi Effects Switcher is a new-concept pedalboard solution that maximizes your creative options by combining a world-class multi-effects engine and multi-pedal switcher in one small, dedicated unit. Now, anyone can assemble a professional effects system that is incredibly compact, extremely light, and versatile enough to achieve nearly any sound imaginable. The BOSS MS-3 Multi Effects Switcher is a sonic powerhouse capable of running six internal pedal effects at once while seamlessly integrating three of your favorite external pedals. It also offers deep rig control capabilities, allowing you to switch amp channels, adjust effects in real time, work with MIDI devices, and more. With the MS-3, it is easy to create a portable board or fly rig without the compromises associated with traditional loop switchers and all-in-one multi-effects units.

As Versatile As You Need to Be

The BOSS MS-3 Multi Effects Switcher’s highly flexible design gives you the freedom to create any effects system, from simple to complex. It can serve as a general-purpose effects unit to augment the core tone from three stompboxes, or function as the central hub of an advanced hybrid rig with MIDI gear and channel-switching amps. It even works as a standalone effects processor, making it perfect for fly dates and other times you need to travel light. And if you are just starting out, the MS-3 provides a solid foundation for effects that can be expanded as your experience grows.

Three Loops for Your Choice of Effects

Via the BOSS MS-3 Multi Effects Switcher’s audio loops, you can connect three different effects devices to the system. You will probably want to hook up your favorite drive and booster pedals to the loops, but you can use any effects you like. Once your pedals are connected, you are able to switch the loops on and off individually and position the MS-3’s onboard effects around them any way you want.

World-Class BOSS Effects Engine

To complement the three external loops, the MS-3 is equipped with 112 effect types to choose from. They are organized into six categories, which are available simultaneously: FX1, FX2, Mod1, Mod2, Delay, and Reverb. FX1 and FX2 contain many different types, from overdrives and distortions to compressors, pitch shifters, Slow Gear, and many others. Mod1 and Mod2 offer the famous BOSS chorus, vibrato effects, tremolo, flanger, phaser, and more. All the effects are fantastic for guitar, and there is also a large selection specially optimized for bass.

Big Creativity in a Tiny Package

The BOSS MS-3 Multi Effects Switcher is packed with decades of BOSS compact pedal and multi-effects know-how and offers an ultra-efficient design that lets you dial in inspiring sounds right away. There is a backlit LCD that clearly shows patch and bank numbers and parameters, plus quick-access knobs for editing and status indicators for all loops and effects. And with 200 patch locations, you have ample memory for storing effects and control setups for instant recall.

Complete Foot Control

The BOSS MS-3 Multi Effects Switcher’s heavy-duty footswitches give you easy command of the entire system. In Memory mode, the footswitches allow you to select patches and banks. Changing to Manual mode lets you switch loops and effects on and off and even control multiple effects parameters for intense real-time expression. Your Manual mode assignments can be stored in patches, letting you create dynamic custom setups for different songs and styles.

Pro Essentials

Going well beyond the basics, the MS-3 provides tons of options for expanded control. You are able to connect external footswitches for tap tempo, effects on/off, and parameter adjustment, plus expression pedals for volume, wah, pitch shift, and more. Control-out jacks are available for switching amp channels and controlling effects that support external input. And there is even MIDI for sending tempo, PC, and CC information to MIDI-enabled pedals, whether they are connected to loops or not. In addition, the MS-3’s two audio outputs can be set for full stereo or selectable mono operation per patch, providing great flexibility with dual amp rigs.

USB and Remote Editing

The BOSS MS-3 Multi Effects Switcher supports USB for accessing the free MS-3 Editor/Librarian software on a Mac or Windows computer. This lets you edit effects, assign control parameters, set tempos, and more via a convenient graphic interface. You can also back up and restore individual patches and organize groups of patches into Live Sets for various gigs.
