I've had my 1982 347 since 2004, and it is still my favourite guitar. The serial number indicates it was built in Nashville. I bought it from a small local store owned by a guy who has an impressive collection of vintage guitars and amplifiers. He didn't have much info on the history of my 347, only that it was previously owned by a female player. It is black and differs from standard Gibson specification in that the pickups, bridge and tailpiece are chrome, and the tuners are Gibson stamped with fly out handles to enable fast winding. An enquiry to Gibson told me that either it was a custom order or an after market mod, so which of those is the case I can only guess at... but there is no evidence of any work, so I suspect it was a custom order. I have never had the pickups out to see what they are exactly, they are hot though, so perhaps series V11.
I love the way the guitar is made, such a luxury feel and look to it. I had never intended to buy a semi solid when I went in the store, but when I tried it, it felt so good to play that I just had to have it :) I only ever use it for recording, given that it is such a weighty guitar (9.7 pounds) I would expect it would not be the most comfortable for live playing, but no problem for me as I only do studio work.
I guess it will never have the cool factor which the 335 has, and Norlin era guitars seem to have a bad reputation, but I could not care less. It is beautifully made, I love owning and playing it, it has more than doubled in value since I bought it, so what's not to like? It's a lovely guitar which I will never sell.
