I have a 97 Guild D4-NT HR that I bought new and recently I purchased two more D4's on eBay. They're in perfect condition. All three of these guitars are built in Westerly, RI. Arch Back. I was surprised at how different the two guitars I just bought sound. One was built in Oct 98 and the other in Nov 98, but they feel and sound like very different guitars. One has a thin neck and feels lighter. It is much brighter sounding. Also, the pickguard is more of a marble than the tortoise I'm used to seeing on Guilds. The other guitar has "True American" on the truss rod cover like my first guitar does and it feels and sounds the same. Most people seem to like the true american one better. Anyway, I was wondering if the true american had anything to do with the difference or was that just how they labeled the guitars for a few years and didn't really mean anything. I expect a little variablity but this is quite a difference. Anyone notice something like this before?
