[Looking for a 12 fret Gibson J45]

Hi there.  Does anyone know where I can track down a Gibson J45 12 fret?

[Is there a list of Artist Signature acoustic models?]

I was wondering if there is a list of Artists signature models for Gibson acosutic? I've seen the big names, but just yesterday I found out the did a short run of "Donovan" J45 acoustics. Does anyone have a list? Thanks so much for your help!

[Can you help me identify this Gibson acoustic?]

Thanks for all the info!!

[Can you help me identify this Gibson acoustic?]

I wan wondering if you could help me identify this Gibson acoustic that I found on reverb. It had a few things that seem inconsistent to me, but you would have much more insight that me.

 

It's a 2008 Southern Jumbo. It has a white label on the inside, it has the banner "only a gibson is good enough" but it does not have the script logo. 

 

Here is a link, any help would be appreciated!

[Neck shape definitions, what are some thinner ones?]

Hi there! When it comes to neck shapes & their definitions......is there a guide anywhere? Round C, Modified V, Slim taper, etc.

Basically I don't like thick necks and if someone could tell me some names of the thinner ones for Gibson acoustics that would be great! I'm good with nut width of 1 & 3/4 or 1.72 etc but I don't like the thicker, chunkier necks. Any help is appreciated!
