Effortless Creative Control
With the classic BOSS ME interface, the ME-90B makes sound design intuitive. Independent parameter knobs in each effect category let you tweak tones instantly, while Manual Mode gives on/off footswitch control for each effect. Switch to Memory Mode to call up full multi-effect setups at the touch of a button. Colour-coded footswitch LEDs ensure easy navigation on stage.
Premium BOSS Effects
The ME-90B is loaded with six categories of pro-level effects that can run simultaneously. Shape your tone with compressors, pitch effects, and filters, or unleash drive and synth sounds for heavier textures. Add movement with modulation, delays, and reverbs, or unlock expressive control with the onboard expression pedal. The Blend knob ensures your direct bass tone stays present, while the send/return loop integrates your favourite pedals seamlessly.
Solid Bass Tone with AIRD Technology
At the heart of the ME-90B is the Preamp/EQ section with 10 AIRD preamps. From vintage to modern bass amps, acoustic-optimised settings, and BOSS originals, this processor delivers authentic tone, rich dynamics, and superior EQ control. Whether you’re looking for clean DI sounds or full-bodied amp character, the ME-90B has you covered.
Perform, Practise, and Record Anywhere
The ME-90B is built for every situation. Connect to bass amps, PA systems, or recording setups with stereo outs and balanced XLR DI. Use USB-C for direct studio-quality recording and playback. Practise quietly with the headphone output, or jam with backing tracks streamed from your computer. Its lightweight, battery-powered design makes it perfect for the stage, studio, or travel.
