Popular YAMAHA Tenor Trombone with a Narrow Bore! Starting Bid: ¥50,000 This is an easy-to-play YAMAHA tenor trombone with a narrow bore. How about a cool matte black custom finish? The water key was removed during painting, so the cork has been replaced with a new one. The slide is in good condition and ready to play immediately. Accessories include only the YAMAHA case; a stand is not included. The exterior of the case is clean, but the interior is not in perfect condition, so please consider it for transportation purposes.
