Here is another Mad Professor pedal, one of the designs which has garnered the most interest around it. Well, it's been gutted and reverse engineered. Unfortunately there is nothing new in the design - it's a pretty standard PT2399 design based off the Rebote Delay 2.5 but it does sound very good.

If you fancy a challenge here's a vero layout by Nocentelli, go on - have a pop!
