1984 is not a fine year according to V experts. The body is alder and the neck is maple. Also the neck shape is unsophisticated and the Dirty Fingers are somewhat gruff. At first I hated the Johnny Winter signature. Then one day I was playing a show with it and I realised it was a really awesome guitar.
I had no idea Gibson were making alder-bodied Vs (or indeed any other alder-bodied guitars) at that time, really surprised by that! :o
yeah, I assume everyone said how Gibson's standards were dropping, not using the right woods, bolt-on neck guitars (M3, Corvus), MDF guitars (Sonex) etc. I imagine it was a bit like now really!
In fact I rather like those 84 Vs, or my one at least. The action can go very low, and to be honest its better put together than my '79 V.. and it has a silky ebony fingerboard!
The SGV is for me kind of like a strat (I'm really into strats these days), but its got enough Gibson features (scale length and frets) to make it easy to pick up. Also it looks wild, where as strats look boring. Its my strat alternative for live playing. For some reason I really like the neck on it, though it is unremarkable.
I should one day get an expert to measure my favourite necks so I know what I like about them :)
I don't know if there's any consistency at all in Yamaha neck shapes, but about 20 years ago I had a Pacifica 604. Didn't have it very long at all, I swapped it for a Strat, but I do remember really liking the neck on it - it was rounded, fairly chunky (although perhaps not so much compared with the guitars I buy now!) but narrow at the nut, probably 1-5/8" like a vintage Fender. I think I like that kind of deep-but-not-wide shape, the complete opposite of a "speed" neck.
It is fairly chunky, and the nut width may indeed be a smidgen narrow - I should measure it.
I think its a misconception that thin neck = fast, thick neck = slow. Obviously there are limits, but you can go pretty thick and still play rapidly. I don't mind a Fender Modern C, but any thinner and I don't like it very much, probably end up playing slower then to be honest.
