Build your base tone with 10 AIRD preamps

The heart of the BOSS ME-90B lies in its robust selection of preamps, offering 10 different tones from which to concoct your sound. From original BOSS models to classic recreations to even acoustic-focused sounds, the ME-90B’s preamp section delivers stunning tones in spades thanks to its cutting-edge AIRD (Augmented Impulse Response Dynamics) technology. Lastly, the ME-90B’s impressive Preamp section is rounded out by an equally powerful assortment of EQ knobs to twist and tweak your tone to taste.

61 studio-grade effects to explore

Once you’ve dialed in your base tone, it’s time to explore the ME-90 B’s sweeping array of 61 top-class bass effects. Effects are separated into intuitive blocks for effortless navigation, including Modulation, Comp/FX1 (compression and pitch-based effects), Filter/FX2, Drive/Synth, and Delay/Reverb, with each block boasting its own set of parameter control knobs. Furthermore, gigging bassists love how the ME-90 B’s onboard expression pedal also features a dedicated set of dynamic effects for in-the-moment experimentation. And to keep your signal clear and defined, the ME-90B offers a global Blend knob that allows you to mix in direct signal with your effect-laden wet tones.

Easy sound creation and flexible real-time control

Thanks to its knob-driven interface and stompbox-style layout, building configurations and tweaking tones with the BOSS ME-90B are a walk in the park. You get all the benefits of a well-appointed pedalboard without worrying about messy connection cables, power distribution, and cumbersome hook-and-loop fasteners. The ME-90B’s eight footswitches operate smoothly and quietly, and its built-in expression pedal provides effortless real-time control over your effects. You can use the ME-90B’s Memory mode to call up complete patch setups using the footswitches, or you can use Manual for direct control of each effect category within a patch. The footswitches on this guitar multi-effects pedal include colored LEDs for at-a-glance identification. Moreover, you can set the LEDs to light in a fixed color for each mode.

With BOSS Tone Studio, you can edit tones, change out amp and effect types, and a whole lot more.
