Although it's a bit captain obvious, I decided to take the time to document my version of a common pt2399 reverb #circuitbend The reason, all the available material is more tricky than need be. Turn a 2 euro reverb board into a delay with feedback control. Good for about 100ms before it gets noisy. I shove these into old synths n stuff. https://poetaster.org/pt2399-hack #circuithack
