the current 914ce can be ordered with an engelmann top & without electronics -
97-00 914c vs 11-12 914ce, the main differences between the 2 models would be
NT neck with scarfjoint headstock vs pre NT on 97-early 00 models
CV bracing vs pre-Standard II (non-forward shifted & no relief rout)
gloss ebony headstock overlay with rosewood binding vs unbound gloss rosewood headstock
bridge pins holes in a straight line vs smiley bridge (pinholes in an arc) on 97- early 99 models
Cindy bridge inlay vs no bridge inlay
bone nut & saddle vs Tusq
Gotoh tuners vs Grovers
in addition to age, the woods on the earlier models are likely to have
tighter & straighter grain, with more silking on the engelmann top &
greater variegation on the rosewood (black, dark brown & purple)
whether the newer model or older model sounds better is up to the person playing
i find that i have more interest in a signature model if it has some features
(unique to a 'standard' model) that have an effect on tone (woods or bracing),
rather than just aesthetics (inlay, finish, etc) & that if i like the tone of a
guitar that an artist is playing & their music, not that i would 'sound like them',
i would be more inclined to research the specs of the 'original' guitar,
whether it be a 68 hummingbird or 68 tele with a maple 'board, etc
imho, it's not just what they're playing, although it is a big part of it,
but it's how they're playing it (in addition to the rig & settings)
