TMS Kobo Original Acoustic Improvement Goods
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 we applied heat treatment.
This is an acoustic improvement good that is inserted between the rotary caps of a horn.
It changes the ease of hitting the note and the resonance.
Usable with Yamaha and Alexander Holten.
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 3,000 yen.
