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.

    Made the Perf layout and it sounds like it should!

    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!

      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!

    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.

    I changed ic still same
    And also i checked all connections in pcb


    Any idea?

      Verified..works great. I do have noise when i turn full potentiometer but might be due to noisy amp

    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 ;)

      Try using an A100K (log taper) for the treble cut/tone control. Much more useful...

      I have to agree. Linear make no sense, use audio (log) taper.

    I also used a B20K (linear taper) for level/volume to get more volume out of this thing.

    Hello! I have a question might anyone of you who understand circuits perhaps try to answer.. I saw it mentioned that apart from the tone control there were a couple of other changes from the original red Llama.. I wonder how these changes affect the gain levels of the pedal? Is the minimum gain (when gain is set to 0) higher on the 25th Anniversary than on the original or MKIII Red Llama? Would really appreciate it if someone would enlighten me! Thanks!
