    Dual mono true bypass with one switch

    2 relay bypass boards would work as well Edit. Or dpdt relay bypass. Doh..

    Dr Robert / Pharmacist Issues

    Reflow all your solder joints. There are some pretty iffy ones on there. No judging but not sugar coating either. Edit, add on Some components look to be held in place by a blob of solder but aren't making contact with the pad. You'll need to use more solder and if you cleaned the board already...

    Conquerer Fuzz - Anyone have a list of all replacements for L1?

    With the SBP inductor having a mammoth part number, I wonder if it's EOL. Banzai has several options, as does Small Bear.

    Roland AD-50 Double Beat

    Yeah. I e heard the same on the LEDs. I bought some to play with on the bread board. Thinking maybe a 5v regulator (LM2931AZ-5?) dedicated to one may isolate it? I'll get around to it one day.

    Roland AD-50 Double Beat

    The coloring on this, *chefs kiss* The only thing that could make it better is one of those color changing rainbow LEDs. How well does it handle a buffer in front?

    Switching Transistors Makes Popping Noise

    That's pretty much the nature of it I think. You can do it with only two poles though. Fwiw, moonn electronics has some rotary switch boards for this if you want to do it in the future. I think they're called "why not more" or just "more" One or the other. Also good to socket one and use it to...

    Median Compressor PCB - Available Now!

    It's a double edged sword with pedals. They're inherently low fidelity. But in non-clipping situations, I try to be mindful of the noise. Higher quality(lower noise) opamps, no mlccs in the signal path, quality low ESR electros if they have to be in the signal path. But that's just me. No...

    Median Compressor PCB - Available Now!

    For comps, it's a pretty good idea to stick to the lowest noise opamp you can. (The 072 was low noise for it's time but opamps have gotten a lot better) Reason being, however much gain reduction you are getting, you then have to make up that gain. The self noise of each opamp stage is going to...

    Foxx Tone Machines - Why No Bias or Starve?

    Try R4 and R13. You'll want to add additional resistance. Maybe a 50k push/pull pot to move the pot from one position to the other? Add parallel resistance in the R4 position to lower the value some. A "dual voiced" starve could be cool. Makes sense in my brain basket anyway... Wait, not...

    SOLVED Gravitation Reverb no reverb

    And make sure you didn't plug in to the out. Easy to do when it's late and the pedal is down side up on the bench With no led, check you switching with a DMM, check you power for reversed polarity(if wrong, check D100 for damage) and check led for orientation. For the switch, power off...

    How to attach FV-1

    Assuming it's pad 26, jumper to the c9 r8 node. And if you lifted the pad for pin 12, just bridge it to pin 11. Watcha got to lose?

    Should I let my pregnant wife help me populate PCBs?

    Lead isn't transdermal. Gloves or proper hand washing and non touching of the face/eating. If you're not using a proper air filtration system, it may be time to bite the bullet, even though times are tight. You can buy a sq meter of charcoal filter foam stuff off of AliExpress for pretty cheap.
