From the post
For #FuzzFriday I give you the SolaSound ToneBender Mk III. The Mark III was a smoother and less aggressive follow up to the famous Mk II Professional. SolaSound built it for several other companies–Vox, RotoSound, Park, etc. There are plenty of layouts for this classic fuzz out there already (there's already 2 on this blog), but I drew this up for a 2-in-1 box I'm putting together (this into a Catalinbread RAH) and thought I'd share. So here's a modern layout for the ToneBender Mk III. Originals used PNP germanium transistors, so the perf side reflects positive ground layout, but the PCB side shows negative ground if you want to use NPN transistors. For more info on the circuit check out this page.
Here's the drilling template for it.
