This item for sale is a Yamaha bass trombone, model YBL-612. This is a professional model bass trombone produced from 1975 to 1984, featuring an offset double rotary valve system (B♭/F/E♭). The 10-inch (approx. 25.5cm) gold brass bell provides a powerful and warm sound. The slide has a standard .562-inch (approx. 14.27cm) large bore size, and the valve system employs an inline paddle system (double thumb trigger). For this sale, I had a reliable repairman perform maintenance. The work included slide adjustment, two rotary valve adjustments, internal cleaning, W/K cork replacement, and case handle replacement. Therefore, the instrument is ready to play immediately. However, as this is a used item, there are minor scratches and dents. Please check the photos for details. Also, due to the recent increase in swap scams, I generally request no returns or exchanges. Thank you for looking.
