Mad Professor Deep Blue Delay

Brand New, never gigged


A natural sounding digital/analog delay, with the analog direct signal path.

CONTROLS

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.
