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.

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

    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. :)

    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)

    verified! I used 2n2222, good! But what sound we have with a lot of details? LIke clean channel
    met "zendrive" overdrive. I can't get enough gain there! I decided to do mod. LF 353 - between 6 & 7 lugs put resistor 18 k, from 6 lug - resistor 5k1 to 1/2 voltage. And resistor with drive pot change from 33k to 6k8 - 10k! Now we have clean channel + more gain!

    I had little definition in the overdrive channel, tested a lot. Did also ZZOYD's mod's and that worked fine but found it still to bassy for guitar. Finally went back to the original design and only changed c34 to 220pf (as claimed in the new version?)
    Used 2n3904's for 2n2484 and TL072 for LF353. (exact parts now ordered)
    Good overdrive sound with it's own caracter....Thanks!
