Yamaha YBL421G Intermediate Bass Trombone

The lacquer
Microscopic, electrically-charged particles of lacquer are attracted to and deposited evenly on the surface of the instrument carrying the opposite charge. This produces an exceptionally thin, uniform coating that can be oven-hardened for maximum durability without compromising the instrument's sound. The sound produced is a solid, somewhat harder sound than silver plate finishes.

The Wrap
A semi-open wrap gives this first level bass trombone a smoother airflow and open sound.

The Slide
The one-piece, drawn, yellow brass inner slide maintains an accurate diameter throughout its length. This type of construction ensures airtightness, smooth action, and exceptional durability and offers improved response. Specially designed, one-piece, inner slide stockings guarantee airtight slide construction, and offer smoother slide action and better alignment, even in the extended 6th and 7th positions. Long-lasting, nickel-silver tubular braces contribute to the stability of the slide and enhance smooth slide action.

The Construction
Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance. A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.

The Acoustics
Yamaha trombones have mouthpipes featuring special acoustic designs allowing for precise intonation and greater blowing control.
