MAD PROFESSOR Deep Blue Delay Handwired

The Handwired versions of Mad Professor pedals guarantee an additional level of quality with circuitry hand-honed by the Finnish brand's engineers. The Deep Blue Delay is a natural-sounding digital/analog delay with an analog direct signal path. The Deep Blue Delay has approximately the same bandwidth as classic tape echo units and can be used before an amplifier or in effects loops. There is no noise reduction circuitry, which keeps the echo decay as natural as possible. The direct signal path is short and built with analog amplifiers without filtering. There is no distortion or tonal coloration as long as the input level is in the range below the maximum allowed. The echo signal has fine-tuned filtering to allow extreme settings without interference. The delay is specially designed to work well even with distorted tones, as this is the most critical application, where delays often fail. The Deep Blue Delay contains the basic functions, Delay Time, Delay Level and Repeat, and was designed to function as an ambient delay; like a vintage tape echo and repeat, it was specifically designed to allow easy adjustment and less critical setting of the delay time. Why digital? Isn't analog better for a solid-state solution? We chose digital construction to make it compact, stable, with reasonable delay times and virtually maintenance-free. A similar circuit in analog form would have been prohibitively more expensive to make. For the same performance, it would have required three to four of the best BBD chips now only available as vintage parts and the size of the pedal about three times the current size.

Controls LEVEL: Sets the level of the delayed signal mixed with the direct guitar sound. DELAY: Controls the delay time from 25 ms to 450 ms. REPEAT: Controls the repeats of the delay signal, turned fully counterclockwise gives one repeat and fully clockwise gives infinite feedback.
