anyway i wish you luck on your hunt for the noise maker


edit:if its quiet on clean sounds it could be something else not your guitar thats making the noise


Well on experimenting around now (Well I'll explain my setup first).

guitar > pod x3 pro (4 cable method) > amp > cab

I'm using a tubescreamer on the pod, all amp sims are disabled. (it's used for effects only). The signal is ridiculously noisy, buzzing, feeding back etc. Whack on the gate and it's fine. So I plug the guitar into the amp, it's a lot better (still a grounding issue but no buzzing or feedback).

The pod is not faulty, works fine with the rest of my guitars. Any ideas on this one?

It is also possible that your solder joints are not making good contact.

Did you clean and prep the backs of the pots before you soldered?

I always use a little sand paper to scuff the back of the pot. Then I clean it with isoprophil-alcohol a few times. I also find myself using 1 drop of liquid flux alot to get a good joint/contact.

The jacks of your pod may be dirty. Spray some contact cleaner on a jack and work it in and out of each jack a few times.

Do you have any other cables that you can try?

If the solder was dodgy then surely it would make the same noise through both the pod and the amp? But it doesn't, only through the POD. Tried different wires, just blew one of my ears out with feedback by activating the tone 2 which had a mic plugged into it though... ouch.

I can't think what it is at all, since it's pretty much none existent through the amp on it's own. Used different guitars through the Pod, fine. Just this one!

There are a few possible reasons most have already been covered here. It could be a case of re-doing all the wiring. I have had to do this on more than 1 guitar.

This site has really good free schematics www.guitarelectronics.com

Also clean the guitars input-jack and see if it helps at all.

Have you added the ground to the bridge yet?

That is the diagram that was used, copied exact! apart from I was told to ground everything to wear the ground of the jack was connected (back of the volume pot). The wire grounding the bridge has not been used because the last Telecaster I had did not have it and had no problems at all (other than the guitar was battered so I decided to change it).

The problem seems to be the tone switch, the guitar has no noise whatsoever when that is turned down other than the guitar playing of course.

I've ran out of wire to connect the bridge to the pot so I'm going to have to buy some more.

It looks like the remainder of this terms student loan is going to have to go on this: http://www.ebay.co.uk/itm/190682613...984.m1423.l2649

That way there can be no problems. Like I said I'm relying heavily on this guitar as a studio guitar and also if needs be live/band practices. On a side note actually, how much difference will CTS pots, CRL, Sprague Caps etc make compared to cheap electronics (which unfortunately were used. (I've had to do this on a budget due to being a student, ran into a few problems too, such as the bridge pickup wouldn't fit into the guitar so that's rammed in pretty much, hopefully it won't do any damage to the pickup however.

You need to ground the tone knob to its self by either running a short jumper wire from the ground lug to the back of the tone pot or by bending the lug back and soldering it directly to the back of the pot.

I always link all the grounds from the backs of the pots togeather and I always ground to each pot.

CTS/Bournes pots are nice, but if it is a sub $1000 guitar I typically use Alpha pots (they are just fine). You will want Audio taper for the volume control and linear taper for the tone pots.

I use Srauge Orange drop caps.

The tone is grounded to itself, via one of the lugs from the cap. Rather than running that to ground on the volume pot, I grounded it to itself as this is how it came on the guitar originally.

The guitar is custom, so the value is more personal. I need the best sound possible though.

I have the right pots, but they were cheap ones

250k a for volume, 250k b for tone

both push pull, no idea of the make, they came from china on ebay, like I said I was on a budget. Got rent, insurance etc to pay first

I can totally understand, I use www.gutarfetish.com alot for cheaper builds

Yeah I've looked on there before, just hope that grounding the bridge will sort it. Dunno what I'll do otherwise, can't really spend 60 on the solderless option for nothing haha

I will pretty much garantee that grounding the bridge will solve most of your noise issues, you may still get some noise , but nothing like you are currently experiencing

The symptoms point to the bridge already being grounded so grounding it will have zero effect.

This is basic physics and electronics.

His bridge is not grounded. he has stated this.

It's likely "grounded" through the paint of the guitar or a pickguard, if equipped with one.

If this is the case, it could very well not be a "full ground" and the body would show some resistence relative to the pot where the "real ground" is.

I've found many super low line copys to have used lead paint........which conducts electricity.

Ask Yngwie......he's local to you and me.

If it weren't grounded at all, there would be no change when he touches the strings.

Basic physics.

Only if there is conductive paint where the bridge makes contact with the body.

And yes there would be a change if the guitar is not grounded when you touch the strings. I have only worked on 100 or so guitars in my life, so I have a pretty good idea of what the simplest ways to check these things are.

Pickguards are non conductive (plactic ones) so it could never ground anything

If there is no ground running to the bridge (spring claw in a trem) that is the most likely culprit of noise you can have.

I have learned on these forums you can never "assume" anything because many people do not know what is really going on with their instuments.

It is you who are assuming and have decided you need to shove your opinion down our throats.

If you've only worked on 100 guitars in your life, then you're arguing outside of your depth.

My post passes the basic physics test.

No I am going off of what TS has said. He stated he did not atatch a ground wire to the bridge. Take it or leave it I really don't care.

And a bridge needs to be grounded unless you have active pickups, that is a fact

Hate to keep springing stuff on you guys BUT after even more experimenting.... it's not the guitar!

Well I'll explain, I thought I should try another guitar and the one screaming to be tested was my girlfriends Ibanez (it's had little use so there should be no problems I thought). Right, plugged mine in, horrible buzzing was there. Plugged hers in (hers has humbucker bridge but 2 single coils in neck and middle) and the buzzing remained. Checked the cables, still remained. Changed her pickup selector to humbucker and it quickly disappeared.

Now this by NO MEANS is purely single coil noise, I've worked with single coil noise before and it's just a hum. This is a loud buzzing. I'm beginning to think that POD's aren't made to be used with single coils.... something in this unit must be reacting with the single coils but not humbucker. I'm going to get on to them and see what they say.
