    Biasing Mofeta Preamp 2N5457

    Hello people, I've been playing around with my Mofeta Preamp and I can proudly say it's an awesome piece of gear. It takes my clean signal and gives it texture and bite, and when I feed it with an octave fuzz, man, it takes that gnarly sound and digests it producing producing a deep, nasty, rich...

    SOLVED Mofeta preamp - Issue with 2N5088?

    Yep, I fixed those values with a 470k ohm and a 100k ohm resistor in series and DUUUUUDE this thing truly roars! Lesson learned, always test components. Thank you all, good people.

    SOLVED Mofeta preamp - Issue with 2N5088?

    Great, I think I found the error. I have some resistors but I had to buy a few uncommon values for this project. I bought them from Banzai, usually they have great customer service but it's not the first time they get mistaken with something. Instead of 562K resistors, they sent me 562ohm...

    SOLVED Mofeta preamp - Issue with 2N5088?

    Those three trimmers seem to adjust the threshold of the eq section, like how many lows, mids and highs get to be amplified by the JFETs, which work fine. They allow you to kinda set the range of the three eq knobs. If you set them too "low", ugly grains sound in place of those frequencies, and...

    SOLVED Mofeta preamp - Issue with 2N5088?

    Hello all, I just assembled a Mofeta Preamp and something weird happens: The pedal has 6 transistors, 4 2N5457 JFET, and 2 2N5088 BJT. When I first tested it, the output was ridiculously low even with everything at max, just a mosquito distortion with the tone pots barely affecting the signal...

    Changes in Mofeta Preamp build documentation?

    Hello, I bought this PCB around May 2021 and waited until the docs came out, which took some time. The PCBs arrived and after some time I downloaded the docs and bought all the components. Now I'm assembling it and I see there are a few incongruences, p.e. the values printed for C11 and C8 on...
