I built a RaD reverb for my dad last year and he has really been getting some good use out of it. Josh at 1776 Effects did a outstanding job with this circuit. It’s simple and sounds great. My dad came to me asking for another one so he could have one pre-looper and another post-looper. What a great idea that is. With that setup you can easily avoid muddy loops and only place reverb on what layer you want. This is what I came up with for him.

I did a etched PCB since I used my last manufactured one. I also did a reverse etch art work of a dude wearing a suit and made the chicken head knob his head.
