Performance-Based Effects for Guitar

From the smallest compact pedal to the most feature-laden rack, the BOSS brand is synonymous with effects that sound great and are built to last. Today BOSS expands its famous ME series multi-effects family with the ME-20, a powerful multi-effects unit optimized for live performance. Easy to use and road tough, the ME-20 provides world-class overdrive, distortion, delay, chorus, phaser, flanger, tremolo, rotary, and EQ effects, taking BOSS’s performance-based philosophy to a very affordable price point.

Simple Operation — Works Like Compact-Pedal Effects

To get the sound you want, simply select an effect and tweak it using the knobs. Turn the ME-20 on, and it’s just like having three BOSS compact-pedal effects side by side. No menus to navigate, no nonsense — it’s fast, easy, fun, and yet powerful.

Famous BOSS sound

The ME-20 provides world-class overdrive, distortion, delay, chorus, phaser, flanger, tremolo, rotary, and EQ effects — all instantly customizable.

OD/DS Solo Function

Give distortion sounds clarity and an intense boost with a simple button press. The first of the three footswitches on the ME-20 is devoted to overdrive and distortion effects. You can also switch the effect on/off via pedal or an external switch (BOSS FS-5U) — great for instantly activating a "biting lead" tone.

EZ EDIT for Quick Sound Creation

EZ EDIT lets you create sounds quickly and intuitively, with incredible ease and speed like no other multi-effects unit on the market. You can adjust a combination of effect parameters with a single knob, and then save your creations for instant recall.

Memory Function

Up to 30 of the sounds you create can be stored in the ME-20’s User memory. In Memory mode, you can use the pedals to instantly select a stored sound. Since the ME-20 makes it so easy to create new sounds, the user memory bank ensures that you’ll never lose those perfect patches.

AUX IN Jack

Plug a CD or MP3 player into this input jack and jam along with your favorite music. It’s also a great way to plug in and play along with your favorite guitar heroes to help build and strength your chops.

Battery Powered Operation

The ME-20 runs on battery power (six AA dry cells) so you can use it anywhere. Wherever you travel, the ME-20 goes with you and never requires an additional AC outlet. For those who want to plug in, however, an optional AC adaptor can be used.
