The MO-2 Multi Overtone is one of those pedals that genuinely does something different. Powered by Boss's Multi-Dimensional Processing, it analyzes your guitar's harmonic content and generates rich, shimmering overtones that range from organ-like textures to flute-like transparency to deep sub-octave rumble. It's hard to describe and incredibly fun to explore.

Three sound modes cover distinct tonal territories: Mode 1 accentuates higher frequencies with sparkling shimmer, Mode 2 hits a balanced middle ground, and Mode 3 pushes into thick, low-end territory. Balance, Tone, and Detune controls let you dial in exactly how far you want to take it. Works beautifully with both clean and distorted tones, and it's equally effective on bass. Stereo output adds extra dimension when you have two amps.
