Got a request for this one for Fuzz Friday. Fairly simple fuzz + boost box. Originals used PNP silicon transistors, but you can use NPNs just as well. The perf side below reflects the original's positive ground and the etch side shows daisy-chain-able negative ground. If you want to put 2 footswitches in a 1590B you could, as the board is small enough for that. Schematic on FSB.
