Way Huge Red Llama

The Red Llama by Way Huge is a great tube-like overdrive with plenty of output. I've drawn 3 layouts–one for every typical Hammond box! The 1590A layout uses 9mm pots which you should be able to board-mount. The other 2 use typical 16mm pots. Make sure to use the unbuffered CD4049 or else the circuit won't work.

  2. Cool. Which size layout did you do?

  3. The 1590B! But I can't see anything wrong with the other versions!

  4. Hmmm, hopefully this comment goes through, sorry if it's a double. Anyway, I don't understand the "LED" spot on the boards. + or -? Where is the other connection? Is it part of the offboard wiring? Thanks in advance for any help.

    1. It's for the offboard wiring of an LED on/off indicator. It takes the place of the resistor in this drawing:

  5. Also, for what it's worth, I tried several times to build this pedal because it was "simple", using several different methods (including a PCB!) and yours is the one that I've gotten to work (1590A). So double thanks!

  9. I built this pedal and I like, 1590B, but I want more fat sound, which capacitor need to be changed? thanks..

    1. Try increase the input (68nF) and/or output (10µF) capacitors

  10. The description says to use unbuffered CD4049 but the layout lists CD4049UBE, doesn't the "B" in "UBE" stands for buffered? If so, may lead to people getting the wrong IC.

    1. You are correct, the B does stand for Buffered, but the U stands for Un.

  12. Just finished one with this layout... very cool. Thanks!!

  13. It should be noted that the Red Llama is more-or-less a clone of the Craig Anderton Tube Sound Fuzz, from his book, Electronic Projects for Musicians, and more specially the second version of the circuit. The EHX Hot Tubes is also derived from this circuit, and predates the Red Llama.

  14. Hi, Could I use normal resistors? or you have to use only the blue resistors?

    1. Use what you want. Blue is just the default color for resistors in DIYLC.
