Mad Professor Deep Blue Delay
Mad Professor's Deep Blue Delay is a pedal designed for electric guitar, but certainly usable across the board with all electronic instruments. Since I've only used it for electric guitar however, this review will be focused on this application of the pedal. It's got a really standard and simple configuration, with 1/4" input and output connections and a nine volt power supply jack. It isn't going to be rack mountable since it's a foot controlled effect.


The make up of the Mad Professor Deep Blue Delay is incredibly simple. It only has three parameters, which might not seem ideal for a delay pedal, but is enough here to get a good amount of sounds. These include knobs for level, repeat, and delay. These are definitely the basic parameters that you'll see for a delay pedal, but I love having as much control possible so I'll never mind a few other parameters. Having said this, it's still a very flexible pedal and is incredibly easy to use because of this. A manual should definitely not be necessary.


The sound of the Mad Professor Deep Blue Delay is incredibly clean! It's the kind of delay that you can hear all of the details of your sound, with each of the individual notes and repeats being heard very clearly. I've used the pedal with a Fender Stratocaster and a '76 Fender Twin Reverb amp, so I think I'm getting a pretty clear picture of what the pedal sounds like. I've only used it in the studio, and it's not cheap so if you're going to bring it on gigs be careful with it (not that it's not sturdy).


If you're in the market for a super clean, high quality delay pedal, the Mad Professor Deep Blue Delay is absolutely worth knowing about. It's definitely on the pricer side of pedals, but Mad Professor has released a PCB version of each of their pedals which is about half the price and of course now much more affordable. I've only used the original version of this pedal, but it seems like the PCB versions aren't too far off. I'd recommend checking out both if possible if you're interested in the Deep Blue Delay pedal.

Mad Professor Deep Blue Delay
This is a digital delay modeling of analog delay upscale.
Level settings is simple: Level, Repetitions and Amplitude of the delay.
Powered by 9V battery or Alime (I use a power supply T-Rex)


The effect is simple possible, everything is in the sound. 3 buttons and a foot switch, basta. The pedal consists of a hull painted a deep blue (hence the name!) Aluminum is both light and strong. No worries about longevity! The buttons are stylish retro respond well to tuning. A red LED indicates operation. No need to leave Saint Cyr to handle it all!


While there, the slap! I wanted a delay in the line of analog delays typed 70's / 80's for their warmth and feeling irreplaceable and I was served! Like I said, it's not analog but a mix of analog and digital. It is a success! Two worlds meet to synthesize a sound awesome. It is a pleasure to see the effect that react simultaneously turns the repeat button for sounds become completely psychotic and barges out of the first Star Trek when it grows back!
The sound is warm, bluesy, rehearsals are both clear and distorted just to give the old school cliché. Magic!
I use coupled with Hardwire RV7 reverb and wah Morley Tremonti and that is happiness!


A little expensive, a little simplistic, but so effective! I was tired of my digital digidelay too bland and then I used a mode 7: analog modeling with rehearsal of a few hundred milliseconds. So I wore my choice on it. I also noted the MXR Carbon Copy but too cold for my taste and the Providence 80's too expensive.
For those who enjoy a simple but effective delay with a crazy shot is the deal of the century! From slapback delay to a second, he won every challenge with gusto ;) Just a pity that there is not a tap tempo, because it makes when the same service. I tested dozens of delays and for the moment this is my reference.
