I own an Epiphone SG Custom in black and gold and decided to add a tremolo that would not damage the guitar. The answer was the FRX from Floyd Rose. While it is not easy to fit IMO and its not a low cost device, the results are stunning. Once its set up the results are incredible. I created a full install and review of the FRX I bought from Thomann here: covers every aspect of the things I found with the FRX whammy from Floyd Rose. There is of course playing at the end too so you can hear for yourself all of the tones and earlier in the video all the install and setup points I came across... A great whammy for particularly SG's but will fit most guitars with a flat top or maybe like a Les Paul.
