Mad Professor Deep Blue Delay Guitar Effects Pedal
Mad Professor Deep Blue Delay Effects Pedal
The Mad Professor Deep Blue Delay is a classic tape-echo-style 60's delay pedal, with natural sounding, old school tones and simplicity. With Level, Delay and Repeat controls, this is a digital pedal, with an analogue signal path. Inspires creativity.
Classic Tape Echo Tone
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. There are no noise reduction circuits, which keeps decay of echo as natural as possible. The direct signal path is short and made with analog amplifiers with no filtering. There should be no distortion or tone coloration as long as input level is in the range below maximum allowed. The echo signal has a tuned filtering to allow extreme settings without interference. The delay is specially designed to work well with distorted tone, as this is the most critical application, where delays often fail. 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.
The Deep Blue Delay contains just the basic delay features; Delay Time, Delay Level and Repeat controls. It was designed to work as an ambiance delay; like that of a vintage tape echo and the repeat, the formation was specifically designed to allow easy setting and less critical setting of delay time. With delay times higher than 120ms, the delay time is sometimes set on the beat or on a multiple of the beat. Deep blue handles this by not giving full range repeats, but a tuned response that doesn't need to be on the beat to sound good.
