Simple Operation — Works Like Compact-Pedal Effects

To get the sound you want, simply select an effect and tweak it using the knobs. It’s the same simple operation offered by compact-pedal effects. Special attention has been given to ease of operation and speed of use — ideal for immediate editing on stage or in the studio.

FX for Bassists

Mix, match, and customize a wide variety of effects for bass, including compressor, overdrive, distortion, T-Wah, phaser, flanger, chorus, delay, reverb, defretter, synth, and more.

BASS ENHANCE Function

This function strengthens bass dynamics with a simple button press, adding richness and impact to the tone. You can also activate the effect with an optional pedal — great for instantly activating a "bass solo" 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-20B’s User memory. In Memory mode, you can use the pedals to instantly select a stored sound. Since the ME-20B 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 bass heroes to help build and strength your chops.

Battery Powered Operation

The ME-20B runs on battery power (six AA dry cells) so you can use it anywhere. You can also use the optional AC adaptor for extended performances. Wherever you travel, the ME-20B 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.
