    Overthinking a simple latching circuit

    Maybe something like a StompBox footswitch, push on/push off? Or the latching circuit from a pedal that uses a momentary switch.

    JST-XH Crimper & Terminals

    Amazon example I found it searching for "lead socket" but the example calls it "pin socket".

    PDF or Web-Based Build Instructions

    I like a PDF for reasons mentioned. Maybe keep ALL revisions available. In addition to the PDF it would be nice to have an Excel (compatible) BOM file, with or without links for individual parts. With links would be kind of a low maintenance Interactive BOM. Actually, if the BOM was posted...

    How much copper is safe in a PCB faceplate?

    Using Star Washers will insure a good ground.

    Building for a pedal for tour

    About the silicone suggestion, Thanks but I can't take credit for it since I got it from an old timer years ago when I was into Radio Controlled aircraft and cars. Think small 10-30k RPM Nitro burning engines that were such great vibration generators they'd make a certain very popular woman's...

    Building for a pedal for tour

    Use some Electronic Grade Silicone, strategically placed droplet sized blobs, to secure longer wires to the enclosure. Great for controlling vibration and mechanical shock related failures. Using small blobs makes future repairs/mods much easier. Also good for securing components into...

    Diode Testing on Breadboard

    Try adding a capacitor in series with the signal in from your sig gen to block the DC offset using your original setup.

    General capacitor questions

    How does it sound? If the answer is "GREAT!" why mess with it? We're not building HiFi pedals after all....

    re-tinning a pre-tinned tip

    Ditto the blob. I go through very few tips, honestly cannot recall last one I had to throw away. I've never had any problem using leaded on a lead-free tip. As @jwin615 said I think they are just ROHS compliant. I don't use lead free so can't say if it's a problem with a leaded tip. Guess...

    Promethium loses signal around r22

    Here you indicate 8.80 volts on the Base but on the schematic you show 7.9 volts. Possibly a cold solder joint? You can check with a meter by putting the probes on the leads (not solder pads, the component leads) of Q3 base and corresponding lead of R11 and measuring voltage with pedal powered...

    Intermittent static in TWO EP-3 PRE style pedals.(just a discussion, not troubleshooting!)(now it’s a troubleshooting thread!😅)

    More questions... Does it make the noise in bypass? When does the noise occur-is it constant or only when you are playing? Does it make the noise without the guitar cable plugged in? Have you checked the jacks-are they loose? If the noise is present with nothing plugged into the input, then...

    Acoustic Preamp Design - Preamp & EQ

    Also interested in this. It'll be worth the wait I'm sure :)

    Intermittent static in TWO EP-3 PRE style pedals.(just a discussion, not troubleshooting!)(now it’s a troubleshooting thread!😅)

    You didn't mention it so I'll ask: have you tested the cable between the pedal and amp? Are you using only the single pedal? Do you have pedals the don't have this static?
