Smooth build for the most part, the board seems needlessly cramped though. Had to mount the 220n cap upside down due to clearance issues and could not get the charge pump socket completely flush with the board because of the neighboring diodes. Also, gotta be careful around the electrolytics...

There's an onboard CLR already (R107), so no resistor needed between switch and PCB, other than that yes to everything :D

First of all check out this image: Now for the rest. You can use common anode LED without issues. Just connect the anode leg of the LED (middle and longest leg) to the A pad on the PCB and wire the two cathode legs (the shorter outside legs) to the outside lugs of the switch (1 and 3 for...

What are those spacers under the foot switches?

Only on the 60 and 100, not the little 25.

Yes, that must be it. The Engl Powerball has a similar switch and in that schematic it's depicted like above, so probably just an error in the Fireball schematic. Thanks, guys!

I assumed if you short circuit a capacitor or a resistor it is essentially out of the circuit because electricity will take the path of least resistance and since the resistance of a bare wire is near 0 that's where current will flow. Then I was looking at the schematic for the Engl Fireball and...

I'm having trouble understanding what's going on with the level and master controls of the Sunn Beta Lead. It looks like inverting op amps to me. What is the purpose of the diodes? And what are the 150R resistor and 2.2u capacitor doing as well as the 47p cap in the master control? Also, since...

Thought I'd post this here in case someone finds it useful. I know I do. It's pretty much just two 20K pots each in series with a 1K resistor to prevent burning out LEDs. Can be used to eyeball indicator LED brightness and find the corresponding CLR value. Just turn the pot until it looks right...

That is a bummer about the ICs. Where did you get them? You can wire the switch without the LED, just the wires from the PCB.

Digging that Sabbath. I may have to put one in my next order. Seems noisy though. You think shortening the leads on the JFET adapter boards would help or is it just inherent to the circuit? Maybe someone else can chime in who built one?

Incredibly tidy! Looking very nice.

The vibrations from the googly eye add a unique layer of top end sizzle to the signal and appear to extend the bass frequencies into the negative numbers. I must tell my friends over at TGP. Tone is in the googly eyes!

It's beautiful 🥲

Truth.

Well, what can I say. It sounds like a rat, looks like a rat, it's a rat! Similar to the PPCB Triad Distortion it's got a switch to toggle between different clipping diode arrangements. Left is one 1N914 in each direction, middle is one red LED in each direction, right is a 1N914 one way and a...

If you have masochistic tendencies you could try soldering some tiny leads to the pins and and hack it 🙃

Maybe a suggestion to @PedalPCB to update the adapter boards to be able to use them with the narrower pitch MSOP8 as well like these double sided ones: https://www.aliexpress.com/item/1005006636105198.html

Thanks, man (y)

If we're talking about the structure switch, this should work: Regular on/off footswitch is wired as usual.
