I have a GC3 that I bought from GC some months ago. As with a few other Taylors I've had, the setup was absolutely spot-on for standard tuning - low and easy with no buzz unless I really dig in. However, I have found that if I go down to DADGAD, the bass E, now D, is apt to buzz a little if hit with anything but a gentle attack. Capoed at the second fret, the bass string buzzes even more. This tended to happen also with a GC8 I owned a few years ago. Has anyone else experienced this - that in standard tuning the factory setup is as low as the instrument can reasonably take without fret buzz, but that there's very little give for detuning?
