The YSL445G features a beautiful rich tone, easy playability, and a balanced response. The bore and bell sizes are the same as professional models, and it boasts a handcrafted assembly which you would normally expect only for a top-of-the-line trombone. The 8-1/2″ bell is made of gold brass for a warm, rich sound which can fill a concert hall and the intonation is very accurate. The slide action is smooth and the quick response and comfortable playability is consistent in almost any register, at almost any dynamic. The 445GE is a medium-large bore model for versatility in almost any playing situation.


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 offers improved response and 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.

The balancer found on the YSL-445G perfectly proportions the instrument’s weight.

Upgraded bell materials
A gold brass bell provides rich sound and flexible response usually reserved for professional models.

Pressure-formed tubing
Perfectly rounded tubing resuslts 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.

Weight distribution
Players are more comfortable playing the YSL-445G trombone because its superb weight distribution makes it easier to hold.

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