DIY projects from old magazines

Hobbyist magazines have published many guitar effects over the past decades. Tube tremolos were a thing in the 1950s, transistor tremolos, wahs and fuzzes in the 1960s and 1970s and so on. Many of these pedals have some resemblance with commercial units, but... We'll see how that goes. I highly recommend you to try and build some of these old circuits. Here I'll present you good, bad and ugly from the past decades. And some of my favourites too.
