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.

Ibanez ST9 Super Tube Screamer

Here's the Super Tube Screamer from Ibanez. It differs from a normal TS9 with the input buffer and the added Mids control. I've laid this out for board mounted pots with a 125B enclosure with top mounted jacks in mind.  Here's the schematic for reference.


  1. It doesn't seems to work. HEEELP

  2. I have just finished it, the pedal sounds amazing! Verified! (I used 50pf instead of the 51pf)

  3. C20k is pretty much unable to get in Europe. Will B20k make huge difference?

    Also worth noting for others, that American pot. marks (A, B, C) differs from European (C, A, F) source:

  5. I have a TL072 and a 2n1308 transistor, when replacing the difference I didn’t notice at all :) you may need to change the values of the elements, but even in this case it works.

    1. at the same time he put the germanium transistor and 100 hfe and 1000 hfe
