Mad Professor Deep Blue Delay

Deep Blue Delay is a natural sounding digital/analog delay, with the analog direct signal path. The Deep Blue Delay has about the same bandwidth as the classic tape echo units, and it can be used in front of an amplifier or in amplifier effects loops.

The delay is specially designed to work well with distorted tone, as this is the most critical application, where delays often fail. You can use the pedal before or after distortion. As such, it will work exceptionally well on clean sounds where requirements are less stringent, especially in terms of echo bandwidth and repeat formation. Its tone has been carefully tuned with a lot of attention to the first critical reflection and how it repeats decay.

• 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.
• Power requirements: 6F22 9V battery or DC eliminator 2.1 mm plug centre negative and positive sleeve.
• Current consumption: 32mA at 9VDC
• Supply Voltage range: 8-15VDC, 9V Recommended.
• Input impedance: 180K ohms
• Output impedance: 10K ohms
• True Bypass
• Signal to noise ratio: 80 dB
