I've scratch built three pedals so far (well, four if you include a buffer). Fuzzy picture below: Orange Squeezer, Dr. Quack, Rat (Rodent - which is the name of my cat). These were pedals I built to fill needs - I wanted a simple compressor, and an autowah/envelope filter, and I specifically wanted a Rat. They work great on my board, which currently is loaded with: Polytune Mini, my DIY buffer, Orange Squeezer, Dr. Quack, Rat, Timmy, Joyo Analog Delay, TCE Nova Repeater, Joyo trem. So.... I am looking for my next scratch build. I am not against kits, per se, I just enjoy the challenge of scratch. My question then, what are some suggestions for my next build that make sense with my current pedal board, something that I can fill a hole with, use it with my current family of effects? I'm sure someday I'll be at the point where I just build stuff and have pedals sitting on a shelf, but right now I want to use what I build. In my component stash I have a handful of old Ge diodes (not exactly sure what type), Si diodes (bunch of 1N4148, some 1N4002), op amps (JRC4558's, TL072's, a single LM308), transistors (couple each of 2N5457 and 2n5458) but I don't mind buying additional stuff outside of that crop. What would you build?
