I recently took delivery of a Tanglewood 12 string (TW145 12 SC) and I am really pleased with it!
it is a small bodied guitar in what they call "super folk" size, with a solid cedar top. The build and finish are excellent (only the pickguard seems a bit "cheaper" than the rest of the build quality)
Sound-wise it's great, a bright sound that really rings out, not so much bass, but with a small body then I guess that's to be expected...
The electronics are B-Band, so good quality, but i can't really comment much on the plugged in sound as I haven't used it live yet.
I tried a number of different 12 strings in this price range (Fender, Yamaha, Washburn, Cort, Ibanez etc) and I think for the money the Tanglewood is hard to beat... The only guitar in the shop that I liked as much was a Seagull 12-string but it cost considerably more.
