Interesting, and a bit surprising replies. I would have thought guitar players thought about these things more, but as a bass player, I have to admit, I really don't care what the scale length of the bass is I happen to be playing. My Alembics happen to be 32", but I have no problem with the extremes of 35", or a 30.5", or a 42" upright for that matter. It's just about adjusting my posture for the job. That 34" scale Hyak fretless is a wrestling match with gravity, but worth it.
Hmmm. Neck profiles. I know more about what I don't like. No teeny-tiny slender necks. I tend to like the wider necks. Probably a product of having played Martin guitars with 1-3/4" nut width for years. I tend to gravitate to guitars with larger necks. I like how the LP's taper.
I agree about the guitars all being their own entity... man, they sure are. Every single one is an individual with its own attributes. I had accepted that beforehand, but I'm trying to zero-in on what makes me like this or that about one or the other of them, and one commonality I keep landing on is a weird preference for a shorter scale. Just trying to understand why. I've tried string gauge changes, even mixing string gauges within sets to fine-tweak tension, action adjustments to compensate for it. My guitars all play great, no complaints, and I can make them so if they don't. Seems like no matter what though, this group is easier to play.
Maybe it's simply the lack of experience. I'm getting there.
Thanks for the insight fellas... the next experiment is underway.
