Yamaha YBL-421G Model Options

• Yamaha YBL-421GS - Same specifications as the Yamaha YBL-421G, except silver plated

Features

• Inner slide: The chrome-plated, nickel-silver, drawn inner slide is very durable and has a quick, sensitive response.
• Outer slide: 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.
• Tubular braces: 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.
• Slide lock: The unique slide lock design on all Yamaha trombones keeps the slide locked in place and keeps it from accidentally falling.
• Bracing: The large, easy-to-hold, nickel-silver bracing guards against possible slide damage if the instrument is dropped and also lessens fatigue while playing.
• Mouthpipe: Yamaha trombones have mouthpipes featuring special acoustic designs allowing for precise intonation and greater blowing control.
• Semi-open wrap: The YBL-421G features a semi-open wrap that allows for an open sound and smooth air flow.
