Amazing Amps, Preamps, & FX: In addition to its stellar COSM amp models and effects, the ME-70 is fitted with a new COSM Preamp section derived from BOSS’s GT-10 and Legend series. With the ME-70 you can dial up a world of tone, from classic to cutting-edge, with simplicity and speed.
Stompbox Ease: It’s powerful and potent, yet the ME-70 offers the ease of a stompbox. The simple knob-based controls for each effect section makes dialing in tone easier than ever, especially with the innovative EZ Tone feature. And when you want to kick in an effect, just step on one of the four footswitches. Think of it as an array of stompboxes melded into one convenient pedalboard.
Phrase Looper: The ME-70’s Delay section is equipped with a dedicated Phrase Looper, which offers a lengthy 38 seconds of recording time. Play a riff, capture and loop it, and solo over it, all in real-time onstage. Amaze your audience with live multi-layered magic.
Extra Expression: Breathe life into your performances with the built-in Expression Pedal. Simply dial up one of the six pre-programmed pedal-control destinations (Wah, Voice, Octave 1, Octave 2, Mod Rate, and Delay Level), put your foot down, and express yourself.
