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
Not much info on this. From what I've read from the BJFE forum is that the 3 knob Sparkling Yellow Overdrive was a short BJFE Customshop run that's supposed to have that old school early American tones, think Fender Tweed, Blonde, and Brownface.
