A multi-effects processor without a menu-driven LCD? Leave it to BOSS to design the most intuitive multi-effects processor ever. With simple knob-based control over each effect section, the ME-50 makes dialing in your tone easier than ever. And when you want to kick in an effect, just step on one of the footswitches. Think of it as a pedalboard full of stompboxes, just without all the individual pedals.

The ME-50 boasts a range of superb COSM overdrive and distortion modes - perfect for use on stage with an amp. Derived from the popular OD-20 Drive Zone, these are some of the crunchiest, tastiest overdriven sounds you can imagine. There's even a "Square" effect for cool synth-type sounds. Of course, the ME-50 also has plenty of other effects like compression, analog delay, flanger, phaser, tremolo, Harmonist, Uni-V and a wicked new Rotary effect.

Having an assignable expression pedal is great, but not if you have to dig through menus just to select the effect you want to control. The ME-50 fixes all that with a simple Pedal Mode switch and knob. First, select whether you want to use the pedal for volume or expression. If you choose expression, you can then select one of six preset assignments via the dedicated knob: wah, resonance, voice, ring mod and octave up or down.

The ME-50's Memory function makes changing Patches quick and easy. Once enabled, the three footswitches become Patch selectors for switching between three programs within one of the ME-50's ten memory banks. To switch banks, just press the Bank Up/Down buttons or use an optional footswitch. And with the ME-50's convenient tuner function, keeping your guitar in tune is easy.
