Annoying buzz! Help! Ibanez PL1770/ProLine

[bdk]

When I got the guitar, there was tremendous buzz. I guessed it was due to the two single coils, so I swapped out with IBZ USA pups, which are stacked humbuckers, voila, buzz on two single coils done. However, there is buzz on the humbucker! I don't get it.

Here's what's weird:

1. Humbucker is buzzing!!!
2. Humbcker buzzes even when played on clean channel.
3. Everything works properly, this is the model with the 5 buttons, + five way switch.

Since all electronics are bolted to pick guard, kind of a pain to test everything. I searched old posts, nothing popped up. Anybody else have this problem? I think it's fairly common, given the fact I just bought a PL2550 which buzzes like a mother too.

Bro, it sounds like a ground isnt there or coming loose. Grounds throw most of that buzz away.

Yea it could definitely be this.
After soldering my output jack into my guitar (it fell out), the guitar now buzzes just like yours from the description, so it is likely that I've soldered the wires wrong and this too could be the problem with yours.
