Rotary Spacer-kun (Titanium) ver2

Limited production and Kobo-exclusive sales item
As a model change, we reviewed the materials to produce a richer resonance. However, there was a tendency for the sound to become slightly harder, so heat treatment has been applied.
This is an acoustic improvement good that is inserted between the rotary caps of a horn.
It changes the ease of hitting the sound and the resonance.
Can be used with Yamaha and Alexander Holton.
We believe it can also be used with tubas and trombones.
Outer diameter 21.5, thickness 1.5, hole diameter 10.5
Made of titanium
Due to increased material costs, the list price is now 3000 yen.
