I have an SG Epiphone G-400 Custom that I want to add some form of tremolo to. I have been researching the Bigsby tailpieces and found out that they use a spring..... Not sure how consistent the tuning would be with one of those. I'm open to suggestion for what to use, but I would like to hear some opinions about the old fashion tailpieces and their consistency in keeping tuning.

Here is the link to my guitar. (If that helps)

My bad. I'm guitarded. I've only been playing 2 years. Awesome setup you got, but how good are they at holding a tune? And can I put one on mine?
