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

LED Polarity. Stickyed above.

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

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...

Using Star Washers will insure a good ground.

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...

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...

Grape StarBurst

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

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

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...

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...

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...

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

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?

Do you have the probe ground on signal ground? On your sig gen is there a voltage offset? Put your o'scope on DC coupling and look at the input signal, it should be 50% above 0 volts and 50% below. Also try moving the resistor from the input to between the diodes and ground. It should be...

Great discussion here! I dont have much to add but this little bit. +1 Dumble frequently used X5F ceramics. Why he chose these over X7R or C0G or ?? is beyond me, but he is known for the tone of the amps he created. I believe that in some cases, as @Chuck D. Bones just alluded to, a certain...

From looking at the schematic: a typical gain control would be placed in the signal path after V1b to set the signal level to V1a. Other than the EQ this signal has no attenuation, deleting it might give you a bit more gain. You can see how much of a gain increase this would be by adjusting...

Guitar, guitar cable(s), patch cable(s), other pedal(s), amp... On method of troubleshooting would be to plug guitar straight into amp see if you can replicate problem. If not add one thing at a time back and test again. Be sure to give each step plenty of time for issue to manifest. I...

You can parallel another 100nf cap with the one currently there for a total of 200nf. This would be a quick test to let you hear the difference. Nevermind, just realized you cant easily access the leads on the cap currently installed.
