I had a Vintage N4 but sold it because the axe I got had problems. But it was a very good model nonetheless, in fact, I would rate it in the top 5 axe I've tried (including the JS
and JEM). OK, here are the specs:
The vintage N4 is alder while the regular is swamp ash. Also its the only N4 that comes wif the orig. floyd rose while the rest are schallers. Tone wise its unbelievable; extremely resonant and f*%king "toneful"! I guess it is because its natural mate finish, which also means you sweat and grim WILL get into the body. Will you sacrifice protection over tone?
Its cutaway neck join is THE best in the market. Period. Not even a neck-thru' can touch it IMO. However, if you get up to the high frets and still wanna maintain the thumb-over position, it may be difficult since it joins the body at the 14th fret, but if you do use a classical method, then you're in heaven! But the neck is 12" radius and its quite thick & beefy, very unlike the wizard profile. Also, the neck isn't finsihed as well.
The body size is also very small and narrow. If you're like 7' gaint or something it may look like a toy, but on my 5'7" frame it is wonderful and very light.
Hope this helps.
