Get a new switch,,
I'd like to know more about this too..
My Gibson switch had no apparant defects,was resoldered "X" times,in case i was having a blonde day, and the rest of the wiring checked/reflowed at joints. On dismantling/ cleaning it still had no apparent faults (!), but, still failed to select the neck pickup properly.
The new (presumably eastern made?) switch had no major, significant physical difference (apart from having less slack in it's centre position, I changed that when i stripped it anyway) .
This switch worked happily from day one and still does with no noise and crackles_
- note that it's only been in the guitar a few months,so I can't say for sure long term.
Slasher, this is the one - a bit better made than the Gibbo.
Switch.
I like these guys, they're fast,most of the bits are good quality (don't like their strat switches) and cheap.
