• Bell taper

The YSL-620 has a continuous taper bell section that improves intonation with even resistance in all registers.

  • 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, and this type of construction ensures airtightness, smooth action, exceptional durability, and adds resonance to the sound.

  • 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.

  • Hand-lapped tuning slides

Hand-lapping slides ensures an absolutely perfect fit and seal between the slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.

  • 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.

  • Rotor

Large rotor on "F" attachment, with a mechanical linkage, allows for smooth transitions from the Bb to F side with less resistance.

  • Hand-lapped rotary valve

The hand-lapped rotary valve provides airtight, light action, allowing quick and smooth valve switching.
