This is a custom up-bell model based on the YTR-135. The bell and braces have been bent, and brass bell braces have been installed. The instrument is surprisingly easy to play, thanks to the unique, vibrant sound of the nickel plating and the improved monitoring performance provided by the up-bell design. It has a striking impact on stage. The pistons function normally without any sticking, but the main tuning slide is a bit heavy. If you wish, a mouthpiece (Yamaha 11) can be included. A case is not included.
