Hey guys, I looked at the pics Tracy posted (thank you Tracy) and it definitely looks just like the SA160Qmam floating in the pic on the left side. I love the guitar, but when I use the whammy the G string goes sharp and won't come back. I tried filing down the nut a little and lubricating it, but it's just not happening. Unless I use the whammy it stays in tune perfectly. However, some songs require me to use a whammy. Can an Edge tremelo be installed on these relatively simple? I also have an 85 RG 550, with a locking nut, but I like the two single coils with the humbucker so I can get both fat, rockin tones as well as the single coil strat sounds. Ideas? Any other models other than the Andy Timmons version have that single, single, humbucker configuration?
