About This Model
The Boss ME-20B is a bass guitar multi-effects pedal built specifically for live performance, featuring 24-bit AD/DA conversion with Boss's Adaptive Focus method at 44.1 kHz for clean, full-frequency signal processing. It packs a suite of bass-focused effects including Synth, Octave, Defretter, T-Wah, and Bass Enhance, alongside 30 user memory locations for storing patches and an EZ Edit knob for fast sound shaping on the fly. The rugged metal chassis houses three footswitches, five real-time control knobs, and a built-in expression pedal, while an AUX IN jack lets you plug in a phone or audio player for practice or reference. Outputs include L/Mono and R quarter-inch jacks plus a headphone output, making it equally useful on stage or at home.
A great opportunity to own a Boss ME-20B at this price point.
