The MS-3 from Boss is an innovative pedalboard that combines a powerful multi-effects engine with a multi-pedal switcher into a single unit.

It's possible to run six simultaneous effects from the pedalboard, alongside 3 completely external pedals.

Onboard there are 112 built-in effects including delays, reverbs, mod/pitch effects, overdrives, distortion and much more. The Built-in tuner, noise suppressor, and global EQ only add to an already impressive product.

There's also a Backlit LCD and panel LED's for on/off status of loops and effects.

Connectivity wise there are numerous jacks for channel switching and effects controls alongside MIDI outputs and USB for patch creation (using the free MS-3 editor.)

Boss MS-3 Product Overview

The 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 put together a professional effects system that’s incredibly compact, extremely light, and versatile enough to achieve nearly any sound imaginable. 

The MS-3 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’s easy to create a portable board or fly rig without the compromises associated with traditional loop switchers and all-in-one multi-effects units.

A highly flexible design gives you the freedom to create any kind of effects system, from simple to complex. It can serve as a general-purpose effects unit to augment 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’re just starting out, the MS-3 provides a solid effects foundation that can be expanded as your experience grows.

Via the MS-3’s audio loops, you can connect three different effects devices to the system. You’ll 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’re able to switch the loops on/off individually, and position the MS-3’s onboard effects around them any way you want. 

To complement the three external loops, the MS-3 is equipped 112 effects types to choose from. They’re organized in 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 and vibrato effects, plus tremolo, flanger, phaser, and more. All the effects are fantastic for guitar, and there’s also a large selection specially optimized for bass. 

The MS-3 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’s a backlit LCD that clearly shows patch/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.

The MS-3’s heavy-duty footswitches give you easy command of the entire system. In Memory mode, t
