This is a booster made with B'z's Tak Matsumoto's attention to detail. Works perfectly. No issues with the knobs, switches, or lamp. It hasn't been used much, and while there are some fine scratches on the front, it's in overall good condition. Please check the photos for detailed condition of each part. Everything in the photos is included: box, instruction manual, warranty, and top hat. Since production has ended, a beautiful, complete item like this will become even more valuable in the future. Thank you.
