Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
This really doesn't need an introduction, one of the most iconic and important effect pedals to have ever been produced and an essential part of Jimmy Page's tone on at least a couple of well known Led Zeppelin albums. If you don't have one then just build it. Get a measured set of PNP germanium transistors to get the most out of it. If you are using lower gain transistors reduce 100K Q2 collector resistor, maybe consider a trimmer instead to fine tune.
Fuzz Central suggest the following mods and the trimmer would seem like a good idea to me to accurately bias Q3:
470R changed to a 1K for more volume
8.2K changed to a 25K pot for external bias
