This is a Yamaha Silent Guitar, model "YAMAHA / SLG200S NT (Natural)". I purchased it used last month, replaced the strings, and put in new batteries (two AA alkaline batteries). I've played it a few times connected to an amplifier. There's no crackling or noise, and the sound is perfect. I think it's a fun guitar to play, with good playability and effects. It's in beautiful condition with no major scratches or stains. It comes with the original case, instruction manual, dedicated headphones, and a hex wrench. Please take a look at the photos and understand that this is a used item before purchasing.
