A semi-open wrap gives this intermediate level bass trombone a smoother airflow and open sound.
The chrome-plated, nickel-silver, drawn inner slide is very durable and has a quick, sensitive response.
The one-piece, drawn, yellow brass outer slide maintains an accurate diameter throughout its length. This type of construction ensures airtightness, smooth action, and exceptional durability and offers improved response.
Inner slide stockings
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.
Pressure formed tubing
Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.
Laser-fused pluzuma welded bell
A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous even vibrations.
The unique slide lock design on all Yamaha trombones keeps the slide locked in place and keeps it from accidentally falling.
The large, easy-to-hold, nickel-silver bracing guards against possible slide damage if the instrument is dropped and also lessens fatigue while playing.
Yamaha trombones have mouthpipes featuring special acoustic designs allowing for precise intonation and greater blowing control.
The YBL-421G features a semi-open wrap that allows for an open sound and smooth air flow.
