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 Red Llama 25th Anniversary Reissue

 Happy New Year, everybody!  This one recently got traced over on FSB. The 25th Anniversary edition of the Red Llama has an added hi cut tone control, but also has a few variations from the original circuit. The hi cut itself is just a basic cap/pot to ground tone control, the minimum gain resistor on the first stage has been reduced from 100k to 91k, and the 2nd stage feedback loop resistance has doubled up from 1M to 2M. Schematic and more info on FSB.

  1. Made the Perf layout and it sounds like it should!

  2. New follower here! So good you posted this since i was planning on building a red llama next. It is going to be this one or the bmp tone stack one you previously shared.
    Also, now that i am here, any chance on getting any layout from beetronics? PedalPCB is now offering a fatbee overdrive pcb, which is cool, but i'm hoping on a swarm layout being published someday
    Thank you and have a nice day!

    1. Please disregard my last comment. I am a fool who had the gain and volume pots switched. Did some surgery and it’s not as pretty but it sounds much better!

  5. I made it

    But theres is over drive but there is also noise like ak47 shoooting..
    Volume and hi cut works but there is a sound like vutvutvutvut.

    And also i checked all connections in pcb

  8. The low pass filter is almost useless. Start to filter at the last 25% of sweep.
    Go for the Red Llama w/Big Muff tone stack, ad a bypass switch, and get a lot more fun and usable Llama ;)
