This is basically for Rich, but I'll take any advice. I have 2 RG750's.
They both have Edge Trems on them, both float, stay in tune etc etc.
But, on one of them, it has a very nice spongy, floaty feel. Very smooth, flutters really well with any of the 3 bars I have on it and it NEVER goes out of tune, and it sets up easily with new strings. It's everything you could want in a floating trem.
The other, well, I have to use a heavier bar to get it to flutter and while it works well, I sometime feels like I'm fighting it. And it's more prone to stick flat or sharp after trem use.
I'm thinking it's the springs or possibly the posts, but they look pretty good. Is there a way to distinguish springs from one another? Are there diffrent ones with different tensions etc?
