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 made with analog amplifiers without filtering. There is no distortion or tonal coloration as long as the input level is in the lower range than the maximum allowed. The echo signal has filtering tuned 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 is designed to work as an ambient delay; as a vintage tape echo and repeat, it is specially designed to allow easy adjustment and a 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 repetitions of the delay signal, fully counterclockwise gives one repeat and fully clockwise gives infinite feedback.
