Getzen Valve Trombone with Slide, Eterna Series/998 This is a used item, but both the valve and slide function smoothly. You can choose to attach either the valve or the slide, allowing for customization to suit various performance styles. While some adjustments could further improve it, it's in good enough condition to be used in a performance as is. A YAMAHA 4G mouthpiece will be included. Please be aware that there are dents and lacquer wear due to age. The included hard case has a broken handle on the long side, so please be aware of this.
