I have also heard from some people that ABR-1 Bridges suck and are buzzy... and prefer Nashville bridges. I have a Nashville on my '78 LP Custom and '79 Explorer, and a ABR-1 on my '72 LP Custom, and I can tell no difference. Perhaps the ABR is a little brighter, but there's too many other contributing factors that could make the guitar brighter in general... 
From ABR-1 to Nashville
The redesign was meant to answer a number of concerns that cropped up with the ABR-1. For some they are quirks, for others they are a reason not to have them: rattling saddles (so they used a retaining clip on each saddle), loose retaining wire (eliminated on the Nashville), not enough travel for a full range of intonation adjustment (so the new one is wider), and thin threaded posts that bend so the entire bridge leans (so the new one has larger posts with integral thumbwheels), and the wood top getting stripped out from the metal threads being put directly into it (hence the threaded inserts). Of course no good deed goes unpunished so the corksniffers want the original design with all its warts.
The Nashville bridge that Gibson currently uses is made by Ping (China?). It doesn't sound or sustain well. The original Nashville that Gibson used to use is the Schaller, it is a better bridge (and more expensive). If you want a good ABR-1 type bridge that fits on Nashville posts, get the Allparts "Old Style Tunematic" in chrome, gold, or nickel from an Allparts dealer. This is a well made bridge (Japan) and sounds great. You can also get the Faber ABR, which fits on Nashville posts, but it costs twice as much as the Allparts one, has prenotched saddles (not good IMO), and the bridge frame is also made in Japan like the Allparts. I like the Allparts bridge, I use it on any guitars I get that have Nashvilles on them.
