The Mad Professor Dual Blue Delay is a powerful and intuitive pedal designed for the progressive musician. It offers two distinctive delay channels with their own set of controls. The short delay has a maximum delay time of 315ms, providing a fatter tone well suited for slapback and old-school tape echo tones. The long delay reaches 810ms and features a modern delay voicing, making it great for lead and ambient tones.
Both delays are equipped with wide-range Tone controls for dialing in the perfect setting. Users can switch between the two delay channels or combine both together for huge dual-delay sounds. Additionally, keeping the On/Off switch depressed for 1 second activates an exciting rhythmic multi-head mode. The pedal also includes a Tap Tempo function for use on the Long delay channel.
The electrical specifications of the Mad Professor Dual Blue Delay are as
follows:
- Supply voltage range: 8.5V to 12V
- Current consumption: 80mA at 9VDC
- Input impedance: 500k OHM
- Output impedance: 1k OHM
The pedal is designed with a simplistic, intuitive form factor and offers a rich, fat, and warm sound. It is well-regarded for its clever and easy-to-use functionality, making it a must-have for instrumental rock and Pink Floyd fans.
