Check out the calculator on the link @pbrommer provided. It uses two resistors, one to lugs 1 & 2 the other to 2 & 3. The two in series will add up to 10k in parallel with lugs 1 & 3.

If you do the math at, say, every 10% of the 10k pot measuring lugs 2 & 3 with a parallel 10k resistor connected to these same lugs you get: 0k || 10k = 0k Loudest, wiper at top 1k || 10k = .91k 2k || 10k = 1.7k 3k || 10k = 2.3k 4k || 10k = 2.9k 5k || 10k = 3.3k 6k || 10k = 3.8k 7k ||...

I cannot see the labels on the red & black jacks across the bottom. I need to be able to read them.

The decoupling cap  isolates DC and depending on uF value can filter certain audio AC frequencies. Type of cap (electrolytic, film, ceramic...) can (depending on who you talk to) effect tone. Edit: capacitor types can be interchanged as long as value and voltage ranges are adhered to...

Another thing to try is using the guitar as an antenna. Use a long guitar cord and walk around the room. The noise should get louder as you get closer to the source. If it's the same throughout the room then go to other rooms and check. If it's the utility box you mentioned you'll even have...

Have you tried the guitar & amp at an entirely different location?

I've got some of these, they feel like a silicone material and are a bit stretchy. (Un)Fortunately I don't have any tubes with a rattle so don't know if they work. But at 44 cents I'd give it a try, especially if I needed to order other things anyway.

Don't write it off yet. All this will have is a line with no input, if that. This scope will have no writing in the display, just the trace. The trace (line) needs a trigger. Adjusting the trigger input and Sync Amp(litude) should get a solid horizontal line. If you'll post a pic showing...

I'm not sure, great question. An oscillation is just a best guess. Typically I see what's there before trying to determine the cause. But something odd is going on to generate a negative voltage and looking at it with an o'scope is much more informative than a meter.

You're correct I was confused. Thank you for this explanation. I took the entire question as a serious question and gave a serious answer, even addressing the satanic part. Once you explained about the satanic part I did catch the humor. The point I've been trying to make is that your...

To be fair I'm not the only one who gave a straight answer to you question before you pointed out you were joking. However I'm the only one you pointed that out to. Anyway cheers 🤙

I get that your intention was humor, but I still don't see where the humor or joking manner is in this post. Looks like a legitimate question to me. The fact that you must explain that it is humor and what the humor is kinda makes my point. BTW other than being somewhat round those things you...

I was actually at a frequency too high to hear, that's why I was asking about an o'scope.

What about the 6 band equalizer? I built a slider version and it works great! With all sliders at 50% it has Unity, moving sliders up gives Gain/boost or down cuts just as one should expect with an active EQ. Clean build, nice looking amp!! Mojotone makes good kits but just like pedals the...

Is Q1 base biased  too high? It looks like Q1 is fully conducting (on). This would indicate too high of voltage on the base. this will give very asymmetrical clipping. What kind of clipping is desired? For symmetrical shouldn't the collector be at ~4.5 - 5 volts? But the pedal sounds good...

I wonder if you aren't getting some sort of high frequency oscillation. By any chance do you or anyone close to you have an o'scope?

Correct. A shielded cable  inside a piece of gear only needs the shield connected at one end. Connecting both ends can create a ground loop which is a source of noise. Do not confuse this with external guitar/instrument cables which do need the shield connected at both ends.
