Nonaka Trading Acoustic Sleeve

This is the Nonaka Trading Acoustic Sleeve.
Developed as an optional part for the old LaRosa model, this part is compatible with specific Bach trombone models and can enhance projection and alter the sound quality.

When actually using the acoustic sleeve, insert it into the opening by pinching it with your fingers and sliding it in before inserting the slide. The acoustic sleeve has a slight difference in diameter between the top and bottom, so insert the narrower end first. Attaching the acoustic sleeve will improve projection and make the sound stand out. It's perfect for playing solos in large halls.

To remove it, insert your finger and hook it to pull it out.

This was purchased as a standalone item before buying the old LaRosa model (originally A47BO) and has been used very little, but there is fading consistent with its age. It does not affect usability.

Compatible Models: Bach Trombone 42B, 42T, A47MLR, 42AF, 50B, 50B0, 50A3, 50T3

*Please note that this will likely not fit instruments other than Bach, so please test at your own risk.
Furthermore, it is currently discontinued, and its compatibility with newer models such as the current 42BOF is unknown.
