This is an Arttech bass guitar I purchased last year from Geek in box, a specialty bass shop. It's an older instrument, so it shows signs of use overall, with scratches and some stains that won't come off. The lacquer finish has hydrolyzed and is slightly sticky. I haven't touched the truss rod since I bought it. The neck is currently almost straight. The case in the photos is included. I really liked this Arttech bass, but I'm selling it because I'm short on money. I will remove the listing if my financial situation improves. Here is the product page from when I purchased it: https://shop.geekinbox.jp/?pid=181959679
