I recently bought an arctic white MIM Stratocaster w/maple fretboard. Found it used, cheap, on Craigslist and always wanted a Jimi guitar so I went for it. Too good a deal to pass up. I didn't think it would be anything more than an extra guitar to fool around on once in awhile, but it quickly became my go-to guitar over my $800 Gibson SG Special Faded with P90's. I've upgraded the jack and the switch to some proper quality parts (CRL and Switchcraft), and changed the tone cap to a Mallory 150 series (I also have a Sprague Orange Drop 418P series that I may try). I've upgraded the pickups to a set of Fender CS 69 and I bought a Duncan SSL-1 to put in the bridge (but haven't installed it yet). So my question is now that the Strat has become my axe of choice, what can I do to it to increase the playability and tone? I'm going for a 60's/70's rock sound, leaning towards gritty/vintage rather than modern/smooth. In other words, what are your top 5 Mexican Strat upgrades? I plan to get a pro setup and a new nut but not until I have it how I want it (hardware/electronics/etc). The tuners don't bother me, the neck is not bad, but I'm guessing the bridge/trem setup is a prime suspect for replacement? Callaham sells a whole bridge/trem assembly for $165 and I may snatch that up. For one it would be nice to have a trem arm with zero play, and two - I've heard great things about those Callahams improving sustain. I don't need sustain for days but the stock bridge/trem seems to kill the sustain somewhat quickly (at least I think it's the bridge/trem's fault).
