The Mad Professor Deep Blue Delay is a hybrid digital/analog pedal designed to deliver an extremely natural and intuitive classic tape-style echo that blends perfectly with distorted tones.

Its greatest strength lies in maintaining a 100% analog, unfiltered direct signal path, preserving your guitar's original tone while the digital echoes musically degrade in the background.
