Thank you for viewing. This is a Gibson Custom Shop Les Paul Special DC. The reason for the "as is" condition is that the neck has been repaired. It does not affect playability at all. As it is a Custom Shop model, it's a very good guitar. It's easy to play, and the wood grain, build quality, and sound are all top-notch. I hate to let it go, but I have too much equipment, so I'm selling it to someone who will play it. There were no certificates or documents when I purchased it used. (I was told by a music store that it is definitely a genuine product.) A case is included, but it's a regular Gibson case, not a Custom Shop case. Please feel free to ask any questions. To avoid any problems, please understand that all sales are final and no returns are accepted. The weight is 4.25kg according to a home scale. It feels quite heavy when you hold it. I believe it's made of good, dense wood.
