Jaicen, I have a quick question regarding electronics: The tone control of the Cort is acting up - adjusting the knob doesn't change the tone anymore. The guitar still outputs sounds, but there's a very loud noise/ hum that doesn't go away when I touch metal parts.

I'm guessing that I need to reheat the solder on some parts, but I want to narrow down which to concentrate on. Any ideas?

I'm guessing it's a bad earth somewhere. Probably one of the wires that's flexed over time. I'd rewire it with quality wires to be sure.

Turn the volume all the way down. Is it dead quiet? I'm probably a jerk for asking but did you try another cable? I'd also check the jack too. That's a weak spot for every guitar I've owned and in my experience more likely to be a culprit.

Take the back plate off and with the guitar plugged in start moving the wires that go from volume to tone and the hot wire to the jack a little bit. touch the back of the volume pot and see if the hum goes away.

I love a complete gut and rewire as much as anybody but it might be a simple deal.

It's not dead quiet when the volume is turned all the way down - there's still some hum. I don't have another good cable to try, but the other guitar with a P90 isn't as noisy as this when plugged in with the same settings. I'll check the wiring later today. Good idea to touch things around, eh_D. I'll try that first before resorting to rewire - been too busy these past couple months.

What do you think? It sounds #dodgy at best

Quote:
in March of 1968, Jimi Hendrix asked a young Seymour W. Duncan to walk his guitar up onstage. That Strat was loaded with pickups Seymour had wound just for Jimi
especially because the article it links to says:

Quote:
someone from back stage brought him out a white Fender Jazzmaster. Jimi hooked it up and wailed through several more songs and the show closed. At the time, I had no idea who the tech was that brought Jimi the Jazzmaster, but it turns out the guy that brought Jimi the Jazzmaster was Seymour Duncan.
It'll still sell though. Don't you worry.


Also, do you know of any manufactures that make the tele (flat top chrome) neck pickups in strat size? I suppose I can go for one of those danelectro lipstick things, but the guitar I'm replicating is a strat that had a tele neck pickup in the middle... but the one I bought is too small, and I'm guessing that's the standard size.

Quality wires?

Stop buying cables by that brand I can't mention or I'll get stalked on twitter.

And yes that's true. Sometimes it's easier to gut the entire thing and start from the beginning... I've considered doing that with the rust relic as I've had to repair the original wiring three times (thanks to a broken FF switch), but I don't think I'm quite experienced enough to wire up a piezo and fuzz factory.

If the tone pot isn't working, then there isn't a whole lot that needs troubleshooting. Check the first diagram on this page. I'd start by checking the capacitor connections, the grounds on both pots, and the wire that goes between lug 1 of the volume, to lug 3 of the tone

Assuming it's wired in a similar way (with the exception of the kill button)

So I did what eh_D suggested: opened up the cavity, made sure that things didn't touch one another and stuff. The hum goes away if I touch the back of the tone pot, but gets louder if I touch the capacitor connecting the volume and tone control?

Anyway, after twisting things around for a bit, the tone control works now (yay). There are still *some* ground issues, as the little bit of hum does go away if I touch the strings or metal parts of both guitars (so it's not exclusive to the Cort, at least)

I honestly believe there's nothing to be done to the grounding as of now - we know for a fact that there are grounding issues in our apartment (like, if I'm on my laptop and my bf's on his ipad and both devices are plugged in and we touch each other, we would feel a weird current running between us ) I guess this also explain the little bit of noise that goes away when I touch the metal parts/ strings of my guitars?

Aside from a power conditioner you're probably gonna have to live with it. I'd bet that the tone cap touched the shielding paint in the cavity. Glad you got it figured out, lots of times it's easy to assume the worst.

That sounds like classic grounding problems, you'll probably find the tone control works its way round and stops working again fairly soon. As I said before, i'd have it all redone properly.
I'd also be looking at either moving or re-wiring your apartment, as that sounds like there's something fundamentally wrong and potentially dangerous with your mains set up. That weird current is one or more of the devices leaking current through your body.

James, those strat pickups are so far from legit, I don't even know what to say. I've never heard anyone mention SD winding Jimi's pickups.

Me neither. I was always under the impression that he used stock pickups in his guitars.

Plus his best sounds were from before that time anyway.

Heh, it's fine at the minute with the exception of that hum that goes away when you touch the pickups.

Another reason I don't want to change it is because it has one of those extra #dodgy fuzz factories like in the original mirror

Yeah, the fix is definitely only temporary. I'll set money aside for new parts and try to have it redone soon. So the noise going away when I touch the strings is classic grounding issues too?

I'll see what I can have done about the apartment. it's only temp housing and I've called maintenance so many times because of various problems

What brand is that? Sounds like a cult

Remember that time Dean From Instagram said he didn't think a certain expensive pack of strings was worth the money, and then they tracked him down?

Same people.

Makes sense. Z switched pot suppliers after Plug in Baby made the FF huge, as people were wearing out the stab pots. True story. If the pictures i've seen are correct, some of the older ones are linear, but the new ones are definitely reverse log (C). Personally I've never had a problem wiring a log pot backwards, but it is what it is.

EDIT: Forgot to mention, demz TOANZ is awesome. I think he should bring back the real amps.
