Hi JW
Cool idea, but I bet it is too much to do (if it is possible) as there are over 800 circuits. And it would mean back tracking through each circuit and creating a database to search ...
Something which may be useful to consider, which I find very useful for myself: I keep a spreadsheet with all my parts stock on, so I can tell if I have everything for a build or I need to get some more of something (because I'm running low). For each transistor or IC, I keep a notes section where I add in all the pedals which use it which I would like to build - (or whether there has been a recommendation from others for use in a particular build)
I also keep all other useful info about components on this spreadsheet, so everything is in one place.
