Product Details

This is the U3 TAMAKI 4.5S, a signature model by Yu Tamaki, a bestseller from willie's. We are offering it to someone who can utilize it due to equipment changes.

U-Cup Design: The unique U-cup shape, which rises at a nearly vertical angle, provides greater freedom for the lips than the rim inner diameter (25.7mm / equivalent to the so-called 4.5GS), achieving rich flexibility.

4.5S Specifications: Features a slightly shallower cup (S). This enhances control and responsiveness in the high register while maintaining the rich resonance characteristic of large-bore instruments.

Sound: Common to the U3 series, it features uniform resonance across all registers and the dense, mellow tone unique to willie's.

In my opinion, this is a mouthpiece equivalent to 4.5GS that is easy to control even for those who usually use 5G or 5GS.

The shank has minor scratches from insertion and removal, but no warping.
There are no noticeable scratches on the cup, rim, etc.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
