    Stone Age Distortion (With messy breadboard + mods!)

    Thanks for this. I just finished building it and it feels wrong. Barely any gain and definitely not sounding like QOTSA. I might just rack it up to experience and move on.

    Summing Op Amp

    Yeah...again...where is it? There is no schematic there, friend.

    Summing Op Amp

    That’s a good idea. Where is it?

    Summing Op Amp

    Thanks, but as I said, I want to combine them in one enclosure on one pcb.

    Summing Op Amp

    Hello, I’m looking to create an summing output, where I can mix two effects, or lower the volume of one, but have the two effects work independently of each until they reach the summing point. In other words, the two effects don’t affect each other. I am building a delay pedal and want to add...

    Missing Build Docs / Schematics

    When we getting the build docs for the Tone Generator? Been months, yo. I need a schematic.

    Any news on the build docs for the Tone Generator? Bought the thing like two months ago.

    Caesar Chorus Build Docs

    Awesome, thank you. So, nothing to do with C3 then? Yes, the breakout board is one I created and I reversed it for spacing reason. That is great catch though. I will start there. However, on the second pedal (not shown) I did wire a PPCB breakout switch board correctly and had the same issues...

    Caesar Chorus Build Docs

    I have just finished building two Caesars and neither seem to be getting a chorus wet signal. I have swapped out every IC chip and transistor on both with working items from reliable sources and I'm still not getting anything. Seems to be the same problem on both units. All LEDs light up and it...

    Were the build docs ever posted?

    SOLVED Valhalla , no led, just noise

    Thank you. However, I am still not clear on whether I should use 9v or 12v power supply.

    SOLVED Valhalla , no led, just noise

    What do you mean by this? I thought you needed a 12v adaptor to power this pedal. Also, on the schematic it says +12v. Am I wrong? A standard 9v pedal plug will work for this pedal? Also, why does the wiring guide show a LM2940 transistor, but the BOM has the L78L12ACZ? Which is it? Super...

    Flickering LED

    Oh wow. Oh wow. Perfect reference. Thank you. That was exactly the sound that was coming out of my pedal.

    Flickering LED

    Hi, I bought some small 3mm leds that flicker, to emulate a flickering flame. Very cool. Tried it in a pedal and it seemed to affect the sound. There was a weird pulsating sound that seemed to “flicker” in sync with the led. Anyone else ever try a flickering LED OR experience any issues?

    IC Units Getting Very Hot

    Thanks. I replaced the two ICs that were hot with two others that I were pretty sure were legit. Works fine now. Lesson learned about buying ICs from Aliexpress.

    IC Units Getting Very Hot

    I have the Circulator built but am getting no sound out of it other than in bypass. I am still checking a few things, but after doing some audio probing last night, I touched the top two LM13700 IC units and they were burning up. Very hot. The third lower one was fine. So, three questions: 1...

    Awful Waffle Issues

    Thank you. Is there a simple way to check that? I don't see any visual evidence of that.

    Awful Waffle Issues

    So, I finished this pedal, had it working okay, although I thought it was a little hot. It was supposed to be a gift for someone. I thought I would try swapping out the regular LED for one that flickers, to give it a flame effect. I tried it out shortly after that and it seemed to work okay...

    Pot Lug Terminal Connectors
