This powerful multi-effects processor features a compact, durable and lightweight design, making it a convenient, portable device for travelling musicians. And, if you want to keep all your gear in one place, then the CB-ME80 padded carry case is exactly what you’re looking for.

Intuitive controls

The ME-90B has an intuitive knob-based interface that allows for easy stompbox-style sound creation. There’s a dedicated preamp section and six simultaneous effect categories with multiple types to choose from. There’s also a blend knob for mixing in the direct bass sound, a send/return loop for external pedals, eight multi-function footswitches, and an expression pedal with toe switch. Plus, creators can use manual mode for pedalboard-style operation and memory mode for switching complete setups.
