Sheena, I'll give it a whack, but bear in mind that I'm more of a bass player so there are many folks here who are much better qualified to address this.
I have a 330/12, which I purchased last year:
It's what some would consider to be the classic Ric 12, no binding or fancy fretboard inlays, a semi hollow body with a single "cat's eye" hole, two vintage style "toaster" pickups, and five knobs.
I'm not sure if you want a description of the guitar's features or my impressions of it, so I'll opt for brevity by just giving you my impressions.
First, the sound has a lovely chimey quality when strummed or picked; it is strung differently than other 12s in that the octave strings are below the main string, which means (for me) that maximum jangle is achieved with pick upstrokes. Second, the headstock arrangement is really cool in that there is a combination of standard tuners and classical tuners rather than the traditional six in a line system used on other 12s; it takes some getting used to, but it is very efficient. Next, as Peter said the playability of the individual pairs of strings is really easy, like a six string electric, but in honesty I have to tell you that the neck is pretty narrow (1 5/8" compared to 1 3/4" on my Takamine acoustic 12), so much so that I find it difficult to play without a lot of warming up. This is my opinion, not meant to be a criticism. Of course, it's a Ric, so the finish on mine is flawless.
Hope this helps.
, and to make the article more representative, i'd like to add the opinions of the owners (or ones who have played it). So can you give any comments - how does it feel to hold this 12-string beauty in your hands? How's the sound in your opinion? Can you tell me, please? 
They DO sound incredible....
