Strangest Feedbcak Problem Ever?!?!

[7stringtechdeath]

SORRY for duoble post... I'm noob and I dont know how to delete a thread...

I have a ****ing massive and strange problem thats been taking too much of my much needed time, and it is very odd.

Ive been having pickup problems for ****ing ages. After re-potting to no avail, I decided to change neck pup (as bridge seemed fine).

I got a SD Jazz, same damn problem.

So I decide, hmm, it must be pots/ switch. I got them replaced today, and wired everything up. FEEDBACK MORE THAN EVER.

( : Feedback more than ever as in, on old components only neck pickup had terrible feedback, with bridge a large amount, but nowhere near what it is now. New components, everything is ****ed, and switch is a bit different, as position 4 has no signal ... but read on to justify this)

In complete despair, I asked a good mate, what could be wrong. He gave me the idea that it could be the amp (Peavey Bandit). So I quickly went over to a mates to try out his amp(Marshall cab + head), with my lead, and what do I hear? ABSOLUTELY BRILLIANT TONE.

( : although wiring may be a tad off (though it shouldnt, its the best job i've ever done, and perfect with the diagram....(yes I know SD wires are different to dimarzio, problem rectified)) the amp worked fine, position 4 still killswitch, but everything is good, and im actually happy with killswitch idea)

In relief, I think, Oh.. its the amp thats ****ed, and it comes off my mind for a few hours.

I then realise I have another amp, which I completely forgot about. I plugged my guitar in, with a brilliant plan to try and amplify my tone with my bandit (as the little amp has headphone jack, and it worked to amplify), and what do I hear?

HORRENDOUS FEEDBACK.

I'm completely dumbfounded. I'm having a practice at a mates tomorrow, so I'll take my Peavey, as I don't think anything is wrong. If something was wrong, the BC Rich 12 watt amp should be fine.

I have these ideas, which seem strange, but in such a situation, i'm just stuck.

a) guitar wiring is ****ed, problem I thought to be initially, most probably something with grounding, but my mates Marshall somehow overcame the problem??. I have spent so many hours re-wiring my guitar, it is basically at perfection right now, however, with new pots and switch, only old components are the input jack, and bridge (relevant due to bridge grounding).

both my amps are ****ed in the exact same way, or my guitar responds differently to my amps than others??? man i'm ****ing dumbfounded.

c) A massive electromagnetic leak in my house??? I tried it em in another room without electrical devices (except for stereo) and still ****ed.

d) all of the above THAT WOULD SUCK.

Anyhow, taking amp and guitar to mates place might clear a bit up, I have a feeling feedback will still be there though... dunno why, it just feels like it. I don't have another guitar to try out, I might ask friend to bring his on weekend or ill put a pickup into my out-of-action guitar to try **** out.

I really hope someone takes time to read this, or at least skim over, and give me some ideas... PLEASE PEOPLE. I HAVE A BIG PERFORMANCE ON WEDNESDAY HOLY ****
