Mad Professor Dual Blue Delay

Mad Professor

  • $ 33995


Rich, fat, warm sound and well thought out functionality make the Mad Professor Dual Blue Delay one of the most clever, intuitive, and easy to use delay pedals currently available.

The short delay has a maximum delay time of 315ms and a fatter tone well suited for slapback and old-school tape echo tones. Long delay reaches 810ms and has a modern delay voicing, great for lead and ambient tones.

Both delays have wide range Tone controls for dialing in the perfect setting. Switch between the two delay channels or combine both together for huge dual-delay sounds. Keeping the On/Off switch depressed for 1 second brings you an exciting rhythmic multi-head mode. A must-have for all instrumental rock and Pink Floyd fans.Tap Tempo function is also included for use on the Long delay channel.

Dual Blue Delay is a powerful and intuitive pedal for the progressive musician.
