BOSS expands its famous ME series multi-effects family with the ME-20, a powerful multi-effects unit optimized for live performance. Easy to use and road tough, the ME-20 provides world-class overdrive, distortion, delay, chorus, phaser, flanger, tremolo, rotary, and EQ effects, taking BOSSs performance-based philosophy to a very affordable price point.
