    125B Chop Shop V2 - UV Print PDF

    Link to the PDF This has an RDG_WHITE layer and a CMYK layer, but no gloss and came out well using Tayda's UV printing service. It was designed around the same Davies 1400 knobs that the Barbershop uses which range from 15mm to 17mm in diameter. Here is a link to the Tayda drill template I...

    PPCB Chop Shop V2 (Fairfield Barbershop)

    No tantalum as far as I am aware. Mostly Wima caps and a ceramic disc.

    PPCB Chop Shop V2 (Fairfield Barbershop)

    I’ve heard lots of good things about this and the circuit seemed different from everything else I’ve built which piqued my curiosity and bumped this one up the build queue. Build: Overall, a fun build. The layout is nice and I had a bunch of JFETs for scavenging in a build I could never get...

    125B Fumble Boost - UV Print PDF

    Here is a UV print pdf for the fumble boost. It has CMYK color and RDG_White, but no gloss. It should be ready to upload to Tayda and/or test with their artwork analyzer tool. PDF Link And the drill template to match the knob indicators...

    Fumble Boost

    1. I populate the board in the usual order of component height: resistors, diodes, IC sockets, film caps, electrolytic caps, etc... and do a visual inspection for any missed or cold solders. 2. I solder the wires to the power jack outside of the case then put the nut over the wires and secure...

    Fumble Boost

    This build was a nice change of pace from my last one, which was a Cornish clone with a packed pcb. This one has just a few parts and came together quickly. I wanted to try this one badly enough that I was willing to try soldering an SMD transistor for the first time. It was not as scary as I...

    AionFx Sigma (Cornish ST-2 (Colorsound Overdriver))

    After playing it for a while at a bunch of different settings, it seems like Cornish wanted to make the pedal cleaner than the original Overdriver. I haven't tried a true Overdriver or direct circuit clone, but the demos of the Overdriver I have seen show it having more clipping than the ST-2...

    AionFx Sigma (Cornish ST-2 (Colorsound Overdriver))

    My main overdrive sound is the green side of a Protein, and then using the blue side if I want a louder, more open tone or using a Kliche in front of it for a more compressed, fatter sound. I haven't built a pedal in a while so I figured I'd audition some new builds to see if anything tops the...

    Stuff you wanted to know but were afraid to ask

    It doesn't look like Inkscape supports moving the origin, unfortunately, so I am stuck with recalculating/measuring. Also, I can't find a drill template on the forum for the Chauffeur so I'd have to measure that from the build documentation anyway.

    Stuff you wanted to know but were afraid to ask

    I'm going to order a few UV printed pedals from Tayda for the first time and was hoping I could get a check on my setup. I've read through Steggo's and Tayda's guides so I have a handle on the various layers and concerns with setting the right color codes. For the 125b pedals I was able to find...

    Scratching My Head! Aion Fx Aurum

    The values of the components around that section look correct, but your C8 looks lightly melted. I think that cap is acting as a low pass filter and if it’s not working properly it might be letting more high end hiss into the signal. It doesn’t look too badly singed (I’ve certainly done worse to...

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    I ordered some more transistors with values closer to the ones in the build documentation. I got two OC140s with these values Q1: hFE=94 Ic=1.0mA Ube=132mV ICE0=28uA ICEs=12uA Q2: hFE=173 Ic=1.7mA Ube=133mV ICE0=37uA ICEs=14uA but it was very gated and fuzzy at all bias/guitar volume levels.

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    That would explain it. If anyone is interested in trading some Fuzz Face PNP transistors for some good NPN transistors please let me know ;)

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    My new transistors arrived: Q1: 2N404 hFE=109 Ic=1.2mA Ube=102mV ICE0=54uA ICEs=8uA and Q2: 2N1309 hFE=333 Ic=3.7mA Ube=185mV ICE0=0.24m ICEs=8uA When socketed, with the bias pot at noon, I can only get the trim pot to 2.2V or so and there's no fuzz whatsoever, regardless of trim/bias pot...

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    Yeah, I bought four hoping at least two would be close but none of them ended up being suitable. I’ve ordered a set of new transistors that’ve been pre-measured to have good values for fuzz face style pedals. I will swap those in when they arrive and report back.

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    Tactical Fuzz - Not Cleaning Up, Trim Pot Issue?

    I recently finished a build of the Tactical Fuzz. It sounds great as a fuzz, but it doesn't clean up no matter how low I set the volume on my guitar (which is my main reason for wanting to build this pedal). I couldn't find instructions for how to set the internal trim pot in the build...

    SOLVED Aion Onyx (Boss Slow Gear) - Pedal Turns On but No Effect

    Thank you both for helping on this old thread. @PJS, I never would have caught the pinout issue on that transistor if you hadn't pointed it out. I was able to switch the source and gate pins and use @Jeffrey 's advice to set the trimmer and now it's working great. It's definitely a finicky...

    SOLVED Aion Onyx (Boss Slow Gear) - Pedal Turns On but No Effect

    SOLVED: For Q2 I was using a through hole K30A transistor which uses a pinout that does not match the placement of the holes on the pcb and so I had soldered this part incorrectly. After correcting my mis-soldering, I used this method from @Jeffrey to set the trimmer pot and get the pedal...
