Here's the thing with buying an MIM Strat, especially on eBay. There are some that have issues. If I had it to do over, I would have just paid the extra $100 and got a new one. At least if there had been an issue, I could have exchanged it.
That's not to say I didn't get killer tone out of it right away. I remember wondering if my pickups were really MIM because they sounded so good. Of course, I was still kind of a noob rocker then. I didn't plan on returning it because it sounded great, but I did find problems.
The bridge piece was a nightmare. The screw holes were on a slight slant to the pickguard, so I was constantly dropping out the high E as I moved toward the neck pup. Also, the trem HAD to be blocked. The intonation became intolerable quickly, just with normal use.
So I had to use all 5 springs and finally block both sides of the trem block to get a decent stop tailpiece. Plus it took forever to sort out the crookedness of the bridge, which ultimately became un acceptable. I finally found that holes 1 and 5 were almost perfectly straight, so I made it a 2-point trem/bridge with the two straightest screws out of that mangled lot.
In short, I had to learn about guitars to make mine playable, but that's not an adventure I would go on again for the price of $100. Plus, with some new pups, it's a happy ending. Everyone should own a MIM Strat. For $500, you should just have one. It's a great playing guitar, extremely versatile for dirty and clean, vintage stuff, blues, classic rock, alternative. The list of Strat players is endless, and it just feels and sounds good to be able to strap one on, even if it's not your main thing.
@bravedude--> That blue one in your picture is my Strat. A MIM Agave Blue with a rosewood fretboard. Yours is probably in better shape than mine, but I love the look of that thing. I was considering a pearloid pickguard. Is your stock? It looks like it might have a swirl to it.
