[quote name='neepheid' post='452777' date='Apr 2 2009, 08:45 PM']It depends how "period correct" you want to be. The Musicmaster was factory fitted with a 6 pole piece Strat pickup under a plastic cover. If you're not bothered about that then the usual upgrade is to put in any alternative Strat sized pickup, like a dual rail humbucker, or a lipstick one. The pics are a little small but it looks like you have some kind of dual rail thing in there already? Anything else and you'll likely have to do some routing and/or pickguard cutting.
If you want it back to before, I have a white cover for a Strat pickup from my Bronco if you want it.
For the rewiring, probably get some nice CTS pots and a Sprague (sp?) Orange Drop capacitor.
To give you some ideas, here is my pimped Squier Bronco -
Full size tuners (I wouldn't mess with the ones in your '71 unless they're not working very well)
BWB pickguard
Lipstick pickup
4 saddle bridge with through body stringing[/quote]
I love the look of your black Bronco. Heres a Bronco ive had a go at I gig with it 3 or 4 times a week. It sounds beautiful
