Looks great! How do you like this circuit? I've been waiting to see a real live build report before jumping on the PCB. Always liked the way the original sounded, just wondering if it's picky about either the germanium or the JFET.

These look great and probably sound that way too! On your MkIII, don't sweat the Q3 bias too much. If you're getting in the neighborhood of 4v on the collector, I can tell that's because you used a low-leakage transistor. In this circuit, I've tried leaky ones, non-leaky ones, and even simulated...

These are so much fun! Love to see gut shots as well...

Cool! Try it out and let me know if it works.

I bet the base and collector need to be swapped...sometimes those Russian transistors have unexpected pinouts! If you try it, just make sure you insulate the two legs you have to cross over each other with some wire casing left over from stripping or something like that.

Super classy Jason! This looks like a fun one to try out.

I think Aion's version replaced the traditional boatload of 10uf electro caps with 1uf film, similar to the Madbean version. So I think Fuzzdog and PedalPCB's are more in line with the original schematic. I know what you mean about the footswitchable octave--I did that on mine and I had maybe...

That is really interesting! I didn't know that the later 2n3565s were higher-gain. I'm hoping to build another one of these soon, so it seems like experimentation could be in order. This circuit does pretty much kill either way. I do hope I can find a decent pink box somewhere, though! ;)

This looks so cool! That is funny about the unity gain issue. The one I built several years back was super-loud (unity at 9:00), and it did have the 1k5 emitter resistor. One thing I'll say about transistors for this pedal--I personally believe it likes mid-gain ones best. Many of the...

Cool build! FYI, orang actually means person or human in Malay, so I guess it would be more like "Sir Human"!

That is a highly appropriate use of yellow knobs! These both look great. Now I'm curious to look back at the Bootleg...

Beautiful build as always! That is some diode mojo going on indeed...

I agree! It sounds really good. I hadn't thought much about this circuit before, but I'm pretty sure I saw recently that Adam Franklin from Swervedriver is using the SFT these days.

Personally I am wondering if you have created a ground loop by grounding both of your in/out jacks to the circuit board. Sometimes this happens with high-gain circuits whereas it would be fine with something lower gain. If you carefully heat the solder joint for the out jack wire on the circuit...

I found a good equivalent for the Tayda yellow LEDs at Mouser when I was doing my Voodoo Vibe clone. It was clear yellow tint rather than the foggy diffused style, and in the neighborhood of 2000-2500mcd. I think it was 2300mcd specifically. These just happen to be close in specs to the Tayda...

I remember over at Madbean that jubal81 figured out something with reverse resistance and the role it plays in how much a diode will clip. You basically measure the resistance going through the diode in one direction, then the other. I don't remember which direction is which, but the higher of...

The worm is the drive, the drive is the worm! But seriously, I heard they are filming a reboot of this as we speak. Loved the original movie, enjoyed the books a lot too...

Awesome build! I love that someone even mentioned a Christina Hosoi skateboard. I'm just going to throw the name Mark Gonzales out there as well...my first skateboard back in 1987! Anyway, I had thought the Kanji for Fox would be a good theme for one of these. There was the X-Files episode...

That is so nuts! I now want to build this fuzz, needless to say. Also, I am traveling to Japan next year, and am definitely going to have to pick up one of these figurines.

Ha! That is really cool. I actually had a Hyperfuzz back when they first came out around '93. I like that you even considered a Mudhoney theme. I have been on a bit of a kick with them lately.
