This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Mad Professor Deep Blue Delay
The Mad Professor Deep Blue Delay is regarded as one of the best PT2399 based delays out there (with the price tag to match that reputation). It's a warm and natural sounding circuit with an analog direct signal path (aka, no buffers), and plays nice with distortion boxes as well. I've labeled IC1 as a TL072 as it's what you most likely have in your parts drawer, but the originals have either OP275 or AD712 for what it's worth. Pots can be board-mounted from the solder side of the board using right angle PCB mount pots.
