    Guess the circuit

    with two clipping diodes and an op-amp, it's likely a son of tubescreamer type thing or a 250/dist+ type thing. I would guess the former, but if you can tell if the clipping diodes are in the feedback loop of the op-amp you'd have more information. Can you get a shot of the other side of the...

    Aldrin Fuzz pcb discrepancies?

    In the build doc photo, there are 8 capacitors in a row. In the picture of your board there are 6 capacitors in a row, and 2 at the bottom corners. So 2 of the 8 capacitors were relocated from the row to the bottom. These two are C6 (5n6) and C14 (2n2). Remaining 6 in a row should be C4, C3...

    Aldrin Fuzz pcb discrepancies?

    the 5.6n is C6 and the 2n2 is C14. They just got moved in your PCBs layout, whereas they were crammed tightly in printed layout.

    Way Huge Jehu Drive

    I got to see RFTC. And I thought I would never see DLJ, but was psyched when they did a reunion tour and caught them.

    How do YOU clean your boards?

    I use no-clean solder, and keeping with the name, I no clean. Sometimes if I get ambitious or it looks really messy I'll use IPA, but that's like 1 in 10.

    I'd use film there

    low gain germanium 2N1304 - worth anything?

    the gains are good for fuzzes--did you measure leakage too?

    Pair: Cap'n Crunch Deluxe and Pipe Stretcher

    When somebody made a best of 2025 builds thread, I realized I had only built one pedal in 2025, and that was a fuzz face for a friend. About time I completed something new. I was able to wrap up two builds this week. It's been a while--my offboard wiring regressed being rusty, so it looks a...

    Best hardware for working with Procreate

    I need better glasses, as I thought this thread was about best hardware for working your prostrate.

    Treble booster options

    Naga Viper is a great one, especially if you don't want to mess with sourcing proper germanium transistors.

    Friedman Mini

    I think @Robert gave one of these away in a contest a few years ago, so maybe he traced it.

    Chop Shop V2 -- first pedal! -- Sounds Great!

    It's all fine and good when you have a 1 pedal like that, but wait until you have >50

    Pedal builders REACT to this guy finally cracking the Spirit In The Sky fuzz

    So is it going to come with knobs or nah?

    Pro-10

    Having built several bluesbreaker type pedals, I was underwhelmed by the blue side of this. The green side is nice though, but I never use it because it's stuck in a dual pedal.

    Happy Holidays! As somebody once said, go build something.

    Where are people getting potentiometers?

    never noticed that issue with tayda branded pots, but I usually stick to the alpha anyway because I figure they must cut something to make them that much cheaper.

    Do you have a one-knob TL071 boost?

    Also, the google query site:pedalpcb.com filetype:pdf tl071 will bring up some of the build docs that have tl071 in them. Looks like one of the top hits (Celsius) is a 1-knob w/ a tl071, as is the Triangulum (both of these also have a chargepump too).

    Do you have a one-knob TL071 boost?

    a microamp comes to mind https://tagboardeffects.blogspot.com/2010/08/mxr-micro-amp.html

    Article 59 Diode Question

    It's not going to impact tone either way, but from the schematic, I'd probably use a 1n5817 there as it's part of the power section.

    Modus Operandi Boost (Jackson Audio Amp Mode)

    good point, I should've considered this, was being too simplistic. and you're right: it's a odd spec to claim.
