This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

SolaSound ToneBender Mk III

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.

  2. Hello,

    Tested - OK
    One sugestion. Please add one capacior series to output, I used 4u7 raster 5 mm then you can use signal (in/out) between "-" with one power line with another box.

  3. I use this layout with some alterations for EQD Park Fuzz Sound. Changed fuzz pot to B1M, changed the tone to volume resistor from 220k to 10K, input filtering resistor from 2M to 1M, 10uf cap to 3.3uf x2, and extended the board to add the TC1044 voltage inverter. I had to use a jumper, but turned out nice. Thanks Effects Layouts!
