Re: getting vintage tremolo to stay in tune?
Well, I say every part counts. Strats are literally designed around the tremolo. Anything that touches the string must be addressed. Fiddle with the claw. Loosen the middle four screws on the plate. Use five springs for pitch return. Sand (or file if you've got the right needle files) your nut slots in a cone with the point toward the bridge, being careful not to cut your nut too low on the bridge side and ruin your action, and lube too. I use KY gel because I live in hope, but have a surplus of the substance, plus it works. Butterfly string trees and those 'e-z glider trees provide minimal friction. Like the man says, keep winds on the machine head post to a minimum, except on those pesky B and E strings. We're talking slot-head posts, right? The whammy bar as designed did not work for me. I went to the vise, like others before , and bent it to a different angle. The way I personally preferred was the reverse of stock, sort of like a shallow 'C' with the whole bar bent up off the top of the guitar for more range. I'm not into diving either, but do it sometimes for fun. All of this worked very well for me, and I know others have done it this way because I copied it off a '57 strat that someone left with me for a month back in the early 70's. It has worked fine for years, but you have to remember to change the strings one at a time or you lose your setup. I've been using my Esquire lately all the time, so I hadn't touched that beautiful strat for a disgracefully long time, but even with year-old strings, that ***** still stays in tune after brutal diving, which I'm not into. Problem is, for gretsch-style trem, you have to learn to be gentle. You have to have a whammy that you don't need to think about.
