This is a Dave Mustaine model Megadeth guitar. I bought it 30 years ago at a musical instrument store in Ikebukuro, and it definitely cost 220,000 yen. For 20 years, I only looked at it a few times a year. When I plugged it into an amp to prepare it for sale, it produced a thick sound. The knobs are not loose. There is no crackling sound. It's a Dave Mustaine spec, and I believe the neck is wider and thinner. It comes with a dedicated hard case. Thank you for looking.
