Thought I'd post up common questions I get asked in the 150+ emails I reply to every day.
2 or 4 con?
If you want access to series/parallel, in/out of phase, or coil taps then 4 conductor is the hook up for you. 2 conductor allows series(normal humbucking operation) only. Traditonally LP style axes have always used braided 2 conductor.
50 or 52mm?
Again, traditionally Gibson spacing has been 50mm(49.5mm actually) and Fender 52mm(again nearer 53mm) so as a general rule I advise wide space-52mm for trem equipped guitars and 50mm for fixed bridge guitars. If in doubt measure from the centre of the High E to the cntre of the low E pole screw.
Does fitting a humbucker cover effect the sound?
In a word, yes. It lowers the resonant peak slightly however we compensate for this with a small adjustment to the wind.
Covers are a great tonal shaping tool, fit one to an overbright pickup can just round the highs slightly and impart and more vintage tone. Similarly removing a cover from a pickup that seems a touch closed off in the top end can open it out a touch.
Covers always need to be waxpotted on if you want to satnd a realistic chance of preventing microphonics. Likewise it's never a good idea to just prise a cover off as you can damage the windings underneath. Send them in and we'll do it for you.
I'll post more as I think of them. :D
