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

The schematic didn't come from the original EQD pedal.
David has recreated the circuit on his website (Perf & PCB Effects Layouts).
You can find his original and verified layout here.
