So this isn't very interesting to most people but for me it's amazing. I've had a 68 reissue Strat since I was 14 years old (I'm 25 now) and while it sounds great and plays just how a Strat does, I've never been able to keep it in tune when using the tremolo.
Now I've been using my PRS' for a year or so now and I love them and they keep their tuning well. So today I thought I'd go about trouble shooting everything on the Strats trem. It's been set up for 11-49's so the nut it cut and filed correctly (though the Low E is a bit too low) so I focused on contact points.
So big bends nut sauce really helped with this, bit of sauce in all the nut slots, where the strings touch the saddles and under the string trees. I also stuck a little spring in the trem arm hole to keep the arm in place and I'm using 4 springs in the cavity with the bridge floating a touch. I also adjusted the 6 bridge screws. The 2 outer screws are just flush on top of the bridge plate and the other 4 are 1/16th (1.6mm or there abouts) off the bridge plate.
So finally after 11 years I've finally succeeded in keeping the Strat in tune! I've tried dive bombing, wiggling and every thing in between to get it to go out of tune but it stays in tune fine. I'm so happy that I thought I'd share it with you guys just in case any Strat guys are in here and they're having trouble with their trems. Thanks :D
