    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...

    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...

    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

    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

    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

    Awful Waffle sounds fizzy

    Finally got this build to work, but I notice that turning the gain up past 9’oclock creates an undesirable fizzy spitting sound. Also the volume is crazy sensitive and very very loud. Is that normal?

    What are some of the easier builds available here?

    I have bought 3 or 4 pedal PCBs only to find that 1) schematics are incorrect 2) parts are hard to come by, or 3) other builders have trouble getting them to work and suggest mods. I don't want to mess with any of that. So, what are some of the easy, fool-proof builds that you have found...

    Sherwood Schematic Error

    Hi everyone, I am new here, but I recently bought the Sherwood PCB and got to building it. I am meticulous about how I go about building and noticed a discrepancy between the diagram downloaded from the internet and the actual PCB. It has to do with capacitors C9 and C14. On the printout, it...
