The Mad Professor Deep Blue Delay is a high-quality pedal designed to deliver natural sounding delay effects for guitarists. With an analog direct signal path and a bandwidth comparable to classic tape echo units, this pedal offers a unique and rich delay experience. The absence of noise reduction circuits ensures that the decay of the echo remains as natural as possible. Perfect for use in front of an amplifier or in amplifier effects loops, the DBD pedal guarantees no distortion or tone coloration within the optimal input level range.
