One year after deciding not to trade in my SSLVO for a Chet Atkins 6120 for several reasons, I have fallen back into my old ways and am once again considering it (I just never got over my 55-year attraction to things Chet). Don't get me wrong -- I love the SSLVO. But it ain't a Chet Atkins model. I just tried a 1959T and am going back with my SSLVO for a side-by-side comparison, but have a couple of questions I hope G-T members can help me with. Thanks in advance. 1. The one I tried at the store wouldn't stay in tune (same thing I noticed last year at a different store), whereas my SSLVO is unbelievably stable, due to the locking tuners maybe? The 1959T has 18:1 Grover Sta-tite tuners rather than locking ones. Is there a locking tuner that fits seamlessly into the 1959T without drilling new holes? So far I haven't seen one with the right specs so I'm thinking not. I won't put any new holes into such a beautiful guitar. 2. And anyone else have tuning stability problems with the 1959T? Maybe the one I tried didn't have a "trapped string" winding or whatever that's called -- I can't remember. If the Grovers are generally terrific then maybe I shouldn't worry about keeping them if I get the guitar. 3. The intonation was off on several strings. Is this even fixable with a rocking bar bridge? There are no length adjustment screws and it has a pinned base, so can this be corrected?
