JazzLab DEFLECTOR / Deflector for Tp, Tb, Sax This item reflects the sound from the bell onto a reflector, similar to playing towards a wall, making it easier for the player to hear their own sound. It's useful during practice, as well as in rehearsals and performances where monitoring your own sound is difficult. The size of the reflected sound can be adjusted by changing the angle of the clip. Purchased new and used only a few times. There are almost no noticeable scratches, but it is a used item, so please understand this before purchasing. The reflector for trumpet, trombone, and saxophone (image 1) is fixed to the bell with a clip (image 2). The outer box is not included, but a carrying pouch (image 3) and instruction manual (image 4) are included. Please let me know if you have any questions.
