Mad Professor Deep Blue Delay Handwired

The Deep Blue Delay is a natural sounding digital delay, with analog direct signal path designed using analog amplifiers with no filtering. With it’s simple and intuitive controls, the DBD gives you easy access to classic delay tones reminiscent of vintage tape and analog delays.

The DBD is specially designed to work well with both clean and distorted tone and you can use the pedal before or after distortion. You can also use the pedal in front of an amplifier or in the effects loop. There are no noise reduction circuits, which keeps echo decay as natural as possible. The echo signal has a tuned filtering to allow extreme settings without interference.

CONTROLS:

LEVEL: Sets the level of delayed signal mixed with dry guitar tone, fully CCW there is only dry (uneffected) guitar signal.

DELAY: Controls the delay time from 25 ms (fully CCW) to 450 ms (fully CW).

REPEAT: Controls the repeats of the delay signal, fully CCW gives one repeat and at fully CW you get infinite feedback.
