Not many guys building electronics here on GT a.t.m - there's a TON of clone schematics and general building resources online.
I know of two guys (in Cpt) who are actively doing things. I've tried and failed 😁 - Bcom ain't as useful as your skills! Getting them reliable and working in a enclosure was a tricky thing for me.
I'd suggest a tube screamer &/or bucket brigade delay as starting point. Useful things to have on pedalboard.
