Mad Professor Deep Blue Delay


MP-DBD Deep Blue Delay

The Deep Blue Delay is a delay pedal that dynamically responds to distorted and clean sounds and has roughly the same bandwidth as the classic tape echo units.

Digital but based on the old analog echo, the best of both worlds. There are no noise reduction circuits what makes the decay of the echo as natural as possible. The echo signal has carefully tuned filtering what allows extreme settings.

The Deep Blue Delay does not give full range repeats but a tuned response making the delay sound great even when not matched to a beat.

At the moment the delay is only barely noticeable, you will greatly enhance the sound with a thick full roundness.

This pedal can be adjusted to any sound and will always improve your sound, whether distorted or clean, extreme or subtle.



LEVEL: Sets the level of delayed signal mixed with straight guitar tone, fully CCW there is only straight (un-effected) guitar signal heard and fully CW gives the loudest delay.

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

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