BOSS - MO-2

DISTINCTIVE, ALL-NEW TONESThe BOSS MO-2 multi overtone pedal is powered by Multi-Dimensional Processing technology (MDP), taking your guitar’s harmonic characteristics and creating a wide range of unique new sounds. Roland’s innovative Multi-Dimensional Processing (MDP) analyzes audio signals in several dimensions and applies ideal effects to each one. By giving different dynamic changes relative to the input signal in real time, MDP can create bold, all-new sounds with a previously unattainable range of expression.
