This is a CONN tenor bass trombone, Lindberg model, and a Protec case. It's an instrument with the CL2000 rotary valve system. The current suggested retail price is 865,700 yen. It has one rotary valve cap, but I'll include a practical metal one. There are two types, but only the metal one with resistance is usable. There's some rust on the edge, but it doesn't affect playing at all. Overall, there are signs of wear and tear and lacquer damage, but the bell and other tubes have no dents, and it's in beautiful condition. The slide has been regularly maintained, so it's as smooth as a Yamaha, even though it's American-made. The Protec case is quite clean, both inside and out. The case alone is expensive, so this is a great deal. The large pocket on the side of the case is convenient for storing a music stand. It also comes with a shoulder strap (stored in the side pocket to keep it clean). In my opinion, it's a higher-end model than the 88H, with a brighter, more core-focused sound, reminiscent of a Back. It's an instrument that can be used universally, whether for solo performances, wind ensembles, or orchestras.
