The BOSS MS-3 Multi Effects Switcher offers exceptional control and versatility in a pedalboard-friendly, space-saving design that is the stuff of dreams. Combining a first-class multi-effects engine and multi-pedal switcher in a single unit, the MS-3 allows you to seamlessly integrate three external pedals whilst running up to six internal pedal effects, simultaneously! As if that wasn't enough, you can also switch amp channels, make adjustments on the fly, utilise MIDI hardware, and so much more. Simply put, the BOSS MS-3 is quite brilliant.

Control and versatility

The heart of the MS-3's enviable flexibility is down to its cleverly designed system of control, ranging from simple to devilishly complex. Whether you want a simple central control unit for your stompboxes, or want to build the ultimate multi-platform rig with multiple amp-switching, the MS-3 can do it all. Even if you wanted to leave your other gear at home and take to the stage with the MS-3 alone, you'll find it is more than capable of getting you through a demanding recording session or gig, effortlessly.

As we've come to expect from the team at BOSS, the MS-3 boasts an impressive chassis with robust footswitches that are designed to take a pounding underfoot. There are two modes to choose from: Memory or Manual. In Memory mode, the footswitches enable you to assign and select patches and banks. In Manual mode, you can switch loops and effects on/off, whilst controlling various effects settings in real-time. Custom patch storage means that you can layout everything within the system to your exacting specifications, catering to different tracks and styles.

Exceptional BOSS effects engine

The BOSS MS-3 is packed with 112 effect types for you to take advantage of - suitable for both guitar and bass -, covering: delays, reverbs, modulation and pitch effects, overdrives, distortion, and much more. As noted above, you can leave the pedals at home and crack on with the MS-3 as a standalone multi-effects unit.

Effects editing

Across the front panel you'll find a backlit LCD display, which indicates patch/bank numbers, and parameters. With 200 patch locations to choose from, you're not short of options to choose from. Thanks to the built-in USB connectivity, the MS-3 can be connected to your Mac or Windows computer, which in turn allows you to access the MS-3 Editor/Librarian software. You can edit effects, assign control parameters, dictate tempos, all via an intuitive interface. Save and/or restore patches, organize patch groups, and set up your MS-3 as you desire for easier control during band practise and gigs.

Essential control

The BOSS MS-3 Multi Effects Switcher is everything you could want in an affordable, professional grade, gig-ready unit. Used either standalone or at the heart of your expansive live rig, it opens up a whole new world of opportunities for you to explore. Whether you want to incorporate analogue, digital, or MIDI-enabled gear, use a single- or multi-amp setup with mono or full stereo operation, the MS-3 can do it all. All that can limit you is your own imagination.
