Re: If you were a poor boy, could just put pups in a Squire Stratocaster what pups?
So you have a vintage 62 Strat, and you plan to buy a 50 dollar Squier strat to sound BETTER?
You aren't going to get a decent Squier for 50 bucks. The only thing you would get near is a used affinity, and those are not going to hold up to serious gigging. You might get a used good condition Squier Standard Strat for around 130-170 if you find a really good deal. You will have to invest more in the pickups and pots than you do the guitar. I have an older Squier Standard Strat that I stuck a CustomCustom and 2 Fat 50's single coils in. It sounds as good as my American Fenders. It is NOT what I would grab if I were playing a gig.
What amp do you play through?
I'd take an Affinity over a standard any day.
Squier Standard - Alder or Agathis full thickness body. The Agathis ones I've had ran the gamut in tone. Some were pretty dark, one was piercingly bright.
Squier Affinity - Alder thin body.
Standard - Two point bridge that tends to experience cracking in the wood where the posts are. (Yours doesn't? Great. I've had a dozen that did. Filled and converted to 6 screw. Do a Google search for Squier Standard bridge crack and you'll find plenty of examples.)
Affinity - 6 screw bridge
Standard - AlNiCo pickups
Affinity - Ceramic pickups
Tuners - Same on both models
With the bridge issue alone, I'd say the Affinity would hold up better in gigging, and give you a decent baseline for replacement pickups. For replacing electronics, there are bargains to be had, especially if considering imported pickups like Artec. (GFS, Calig, Dragonfire, etc.)
