The Yamaha LS16 is an acoustic guitar with a rosewood back, known for its rich tone. - Brand: Yamaha - Model: LS16 - Body Shape: Acoustic Guitar - Back Material: Rosewood, all solid wood Purchased new from Ishibashi Music in 2020. Action at the 12th fret: 6th string 2.5mm, 1st string 2.0mm, as shipped. Fret wear could not be confirmed, estimated to be over 90% remaining. There are fine scratches on the back, barely visible unless you look closely. Pickup functions normally and produces sound. There are pick scratches on the pickguard. No top bulging. No neck warping. The truss rod has never been adjusted, as shipped. Please ask if you need any other photos. Because it's all solid wood, the sound is dense and beautiful. I'm selling it because I mostly play electric guitars and haven't had the opportunity to play acoustic guitars.
