    Scientific measurements of clipping diode differences

    I've been wondering about a way to test and/or measure what different diodes sound like, and more accurately if they indeed sound different when used for clipping. To elaborate, I know the biggest difference between different diodes we use for clipping is the forward voltage. To simplify...

    Amber Overdrive Midas Touch Mod

    Figured it might be worth asking, does anyone know what the Midas Touch mod for the Mad Professor Amber Overdrive entails? It sounds like probably some component changes, maybe tonestack changes or something else pretty small? Here's the best (non-sales pitch) description I found of what is...

    Tonebender Mk. II transistor clarification

    Yes, I know, there's a bunch of threads and a whole lot of information online. And that's really my issue. I've seen some advice which aims for hFE around ~100 or so, with leakage around 200uA or so, like here...

    Arachnid 1uF -> 470nF

    For whatever brainfart reason, it seems that I ordered 470nF MLCC caps for the Arachnid instead of 1uF. Would I be fine using those, or should I just wait until I can get more 1uF caps? If it helps, I can use 1uF for C6 and one of C10 or C3 mostly easily, the others would have to be two of the...

    Interactive pedal demos

    Found this cool site because the demo was used on a pedal maker's website (TS and Muff in parallel, cool pedal, FreqScene SoftCrush or something) https://loopydemos.com/demos As far as I can tell it's basically a guitar loop recorded multiple times through a real pedal with different settings...

    Open Theremin

    Anyone heard about this? https://github.com/GaudiLabs/OpenThereminV4 https://www.instructables.com/Open-Theremin-From-Scratch-Building-a-PCB-From-Ope/ It's a digital theremin based on the Arduine One, an extra PCB and obviously the antennas, on a tripod. From what I read, it's a pretty decent...

    Skreddy Fuzz Driver

    Note, it's called the Fuzz Driver and it's different from the Hybrid Fuzz Driver. Anyone know what this is? Is it some ancient Skreddy pedal, or just something else that was mislabeled? http://dirtboxlayouts.blogspot.com/2019/09/skreddy-fuzz-driver.html...

    125B PedalPCB Sandblaster Fuzz

    https://drill.taydakits.com/box-designs/new?public_key=NHhqd1kwNW5uemlwVWxtZENXOURHdz09Cg== Verified I compared the 4 knob template (Son of Ben) to the Sandblaster build docs and it seems that they match up, except the LED hole is a switch, there's an another switch, and a led hole lower down...

    Stiff pots?

    Not really directly pedal related, but it could be. A volume pot on one of my guitars is pretty stiff. I'm wondering if there's some tried and true method to fix it? What I found by googling is letting the pot soak in lighter fluid overnight, but that seems kinda overkill, plus I would need to...

    EBS Runsten, 10x 9V 900mA power supply

    Anyone seen this? I've come to the conclusion I probably can't fix my old power supply, so I'm shopping for a new one and this one should at least have enough juice for everything. 8 switchable 9V/12V outputs, two 9V outputs, all isolated, and two USB 5V outputs. I guess the downside would be...

    Is it worth trying to fix a power supply?

    I was using my huge pedalboard a little ago and suddenly it started malfunctioning. Just a slow motorboating type sound, some pedals not lighting up, smelled like burning. I finally got around to troubleshooting in more detail, and it looks like my Truetone 1Spot CS12 is broken. To be more...

    Delay pedal for vocal use

    If I wanted to use a pedal designed for guitar (mainly, say, a delay pedal) for vocals, is there anything else than just switching out the input and output jacks for XLR? And how would that work since it's unbalanced and mono, presumably? Or is a microphone's signal too low to work with just any...

    Tantalums in the Hydra 1uF slots

    So I was a dumdum and did a nono and put in polarized tantalums in the 1uF slots on the Hydra. If I got it right, it's ok as long as the tantalum is blocking 9V from reaching the FV-1 and the output cap stops DC from leaking out of the pedal, is that correct? If I figure which way they are in...

    SOLVED Viceroy very low gain

    Built up the Viceroy, and it passes signal and sounds somewhat like it should if I dime level, gain and juice and toggle juice to be enabled. Toggle juice to disabled, and it's more of a mid gain thing. Lower either level or gain and it gets way too thin. In short, I don't have as much signal as...

    Label stencil using a PCB

    A thought hit me, would it be possible to create a PCB with cutouts for common labels like "Gain", "Volume", "Tone", TMB and so on, with possibly even small holes over them so you can space the text correctly for different sized knobs? Then you could use them as stencils to write the labels with...

    Volume pot useable range

    How do you set your pedal volume pots? Does anyone use the first ~third of the rotation? I think generally it's a preference that unity should be around middle (so 12 o'clock), but I find myself pretty much always using either unity, a bit more, or a lot more, depending on the pedal and use case...

    SOLVED Broken Distortron troubleshooting

    Hello! Bypass is fine, very weak signal when active (with drive and volume dimed, not much if they're not at max). I didn't trace the signal the whole way through since I don't have a schematic (apparently it's based on a BOR without the boost so this should be in the ballpark...

    AI image generation

    I've been messing around with generating images locally (you basically need a decently beefy computer, and a modern gaming graphics card with preferably at least 8GB VRAM, although you might get by with 4GB) lately, since it's pretty fun and free. I'm using them for my pedal graphics, but I...

    SOLVED Sugarbag Overdrive no signal

    First off, I apologize for the abomination of a build. I first put in the 2N5088 in the wrong orientation, clipped off the legs and tried desoldering for a bit, but it didn't work very well so I just soldered a new one on top. I also subbed two of the 1uF coupling caps (?) for 470nF due to...

    Pre-gain high cut to the Informant overdrive

    Hello! I built the Informant Overdrive a while back, but I'm not in love with it. At least with my Strat that I normally use, which is obviously pretty bright sounding, it's not a great match. If I turn down the tone control on the guitar I can get a really nice, smooth, distortion with a lot...
