Boss MS-3 Multi Effects Switcher

A Great Multi Effects mixer

The Boss MS-3 Multi Effects Switcher is designed to maximise players' creative freedom, combining a powerful multi-effects engine with the flexibility of a multi-pedal switcher. With extensive effects and connectivity, the MS-3 makes it possible for anyone to create a professional effects system both compact and versatile enough to suit a wide range of playing styles. Capable of running 6 different onboard effects alongside three of your favourite stompboxes, the Boss MS-3 can stand against the most powerful units on the market. Set it up as the foundation of your rig or as the main control centre, or as a standalone unit for times when you need to travel light. Also featuring the MS-3 editor/librarian to organise and customise the pedals effects, the Boss MS-3 Multi Effects Unit is perfect for both new and seasoned players.

Extremely Versatile Design

The highly flexible design of the MS-3 allows players to create a wide range of effects systems, from simple setups to fully complex rigs. Use the multi-effects switcher as the central hub of advanced hybrid rigs with MIDI gear and channel switching amps, or as a general-purpose effects unit to improve the tone of up to three different stompboxes. Simply connect your favourite stompboxes to either of the three FX loops and position the onboard effects around the loops in any way you want. The unit can also be used as a standalone effects processor, perfect for times when you need to travel light.

Powerful Range of Onboard Effects

Equipped with Boss’ world-class effect engine, the MS-3 features 112 effect types split between 6 different categories, FX1, FX2, mod 1, mod 2, delay, and reverb. FX1 and FX2 offer a range of distortions, overdrives, compressors, pitch shifters, slow gears and many more to saturate your tone with extra characteristics. Mod 1 and mod 2 features Boss’ famous chorus and vibrato effects, along with tremolos, flangers, and phasers to enhance the dynamics of your playing. Although the effects are optimised for the electric guitar, a large section are specially optimised for the bass guitar.

Built for an Easy Play

Even with its extensive capabilities, the engineers at Boss have kept the interface as simple and easy to use as possible. A brightly backlit screen clearly shows the patch/bank numbers and parameters for easy changes, and quick access knobs make editing incredibly simple. Heavy duty footswitches provide easy command over the entire system, with options between memory and manual mode to change the effects of the footswitches. When in memory mode, the footswitches can be used to select patches and backs, while manual mode allows players to switch loops and effects on/off. All these settings can be saved within the 200 patch location on the MS-3, perfect for ensuring your favourite setting can be recalled when needed.

Excellent Connectivity

An extensive range of ins/outs provide the pedal with plenty of options to expand control, allowing players to setup their perfect rig. Connect external footswitches to control tap tempo, effects on/off, and parameter adjustments, or attach expression pedals to add extra dimensions to your tone. Control out jacks are perfect for switching amp channels and controlling effects, while the MIDI out allows connection of MIDI enabled pedals. The addition of 2 audio outputs make the multi effects peal perfect for dual amp rigs, letting you switch between mono and stereo. The addition of a USB port lets players access the free MS-3/librarian software to edit effects, assign control parameters, set tempos, or backup and restore individual presets.
