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.

Way Huge Pork Loin

Here's a really big one to kick off the week (might be the biggest dirt circuit I've ever laid out). The original Pork Loins have the Clean Tone, Presence, and Drive Mix pots internally, with 3 internal pots internally, and I've gone with the same configuration here. Schematic can be found here on FSB.


  1. shit man, this one looks intimidating to do on perf. Wich means I'll probably build it this way, hah!

  2. How many details, for the drive))

  3. anyone know a good source for the 2n2484 trannie?

    1. Tons of them on Ebay from US sellers.

  4. Mouser has them, too. A bit pricey. I read over on Madbean that someone built in with 2n2222 but preferred the original for lower gain settings. Several Way Huge pedals utilize them, notably the fat sandwich, which I've only see one large vero layout for. :)

  5. Newark also has them - better price but they have a $25 min shipping charge... :(

    I wonder if a 2N3904 would be ok... similar hFe range (40)... much less that the 2n2222 (100 hFe)
