For easy identification, each footswitch features a distinct LED color, which can be set to a fixed color for each mode if preferred.

The ME-90B is equipped with a selection of premium BOSS bass effects, organized into six logical sections for simultaneous use. From essential tone shapers like compressors, pitch effects, and filters, to more aggressive textures with drive and synth effects, this pedal has it all.
