hey guys, I have a huge problem and would like some help. I recently fitted a set of Lace sensor hot golds to my squire, i tested it and worked OK. then i decided to fit a push/pull pot to get N/B in to play, so while i was doing this i fitted a new set of 500k A pots and a new 47 pico farad Capacitor. Now here is where the fun starts. All lines test perfect on the ohmmeter, but when i plug in to my Super champ XD and my friends line 6 spider i get a weird feedback. any movement of the tone pots feedback at any setting other than 0. volume at full different feedback than volume at 1-9 lead is fine amp is new I'm really stumped by this and could really use some insight if anybody has any clue. thanks guys

TS-
Hello and Welcome!
I'm stumped, too. At first, I thought "too close to the strings" with the new pickups, but then I re-read it. Since you indicate it was working before adding the P/P pot, I don't have an explanation for why that change alone should make a difference, assuming it's wired properly.
Please post what you did to rewire it, via diagram and/or close-up photos, and maybe we'll see something amiss. Failing that, you may have to go back to the original configuration (before adding the P/P), ensure that it's good there, and then work forward to reinstall it.

ts, Hi, and to the NutzHouse! Exactly where did you insert this 0.0047µf capacitor? In fact, can you post the diagram you followed when making your mods? An alternative would be to post a few photos of your guitar's innards. Best of all worlds would be posting both, the diagram and some pix. sumgai

Thanks for stopping by.
On top of what was requested above, please also post some definition of the word "feedback". A soundclip would help quite a bit, but just a few (more) words to describe what you're hearing could help a lot.
Many people will use the word "feedback" when they mean "noise".
Noise can manifest as a humming or buzzing or hissing sound. It can sometimes seem to have a note of its own, but is almost always there (when a real problem) both when playing and when not. It (when a real problem) comes from uncorrelated EM radiation bombarding - and being amplified by - the circuit.
Feedback is when one or another part of the system is "picking itself up" - amplifying and then reproducing (and then amplifying again...) the same signal. This will be a squeal or howl or a ringing kind of sound, and is usually not so noticeable when you're playing.
Also, does touching the strings or other metal parts make a difference.

the diagram was a standard Strat wiring. since im an aircraft technician i worked out the P/P switch myself. i have a couple of images and a sound file or two to upload. the problem has changed slightly today. the noise is now mostly in the neck pick up.
since i seem not to be able to post the images i will email them

ts, For instructions on exactly how to post an image (or as many of 'em as you wish), go here: How to post an imageImages are directly supported by the Forum's software, but for sound clips, it's a bit different. You'll need to post them elsewhere and simply link to them as if they were a webpage. The person reading your post then clicks the link, and hears the sound file. If I'm not mistaken, soundclick.com is one site where you can do this..... but since I don't do audio myself, I could be mistaken about that website name. I'm sure others here will correct me if I'm wrong, and give you the correct name. HTH sumgai

ok so i have fixed the humming was a stupid solder joint. but...... now the tone is acting more like a volume knob. But i will sort that problem tomorrow today i just want to play it and see how the pups sound
