Adaptive Distortion


Perfect Distortion Tones in Every Register

Powered by Multi-Dimensional Processing technology (MDP), the DA-2 Adaptive Distortion delivers ideal distortion tones wherever you play on the guitar neck.

Multi-Dimensional Processing for Superior Tone

Roland’s innovative Multi-Dimensional Processing (MDP) analyzes audio signals in many dimensions and applies ideal effects to each. 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.

DA-2: Ideal Distortion Across Your Guitar’s Entire Range

Unlike standard distortion pedals that process the entire guitar signal with one effect, the DA-2’s Multi-Dimensional Processing employs multiple distortion processors to seamlessly adapt the sound in real time and create the ideal tone for every register. As a result, the DA-2 delivers a rich, musical distortion that plays well all over the neck, from tight, edgy low-string tones to fat, smooth highs for lead playing. With the power of MDP, the DA-2’s distortion is dramatically responsive to your playing dynamics, and every note is heard with clarity and definition.
