Features
Inner slide
The chrome-plated inner slide is very durable and has a quick, sensitive response.
Outer slide
The one-piece, drawn, nickel outer slide maintains an accurate diameter throughout its length, and this type of construction ensures airtightness, smooth action, and offers exceptional durability and 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.
Hammered bell
A hammered, yellow brass bell produces a slightly more intense, yet pure and perfectly-balanced tone with quick response and extra presence due in part to advanced manufacturing techniques.
Hand-lapped valves and 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.
Rotary valves
The YBL-612R has two hand-lapped large rotary valves to ensure less resistance and quicker response in the "F" section

Specifications
| Keys | Bb/F/Eb | |
|---|---|---|
| Bore | .563" | |
| Bell | The 10" gold brass bell has a soft, mellow tone. | |
| Inner Slide Material | The inner slide material of the YBL-612R is chrome-plated nickel silver. | |
| Outer Slide Material | The outer slide of the YBL-612R is nickel silver. | |
| Gold epoxy 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. | |
| Gold brass leadpipe | Gold brass is extremely resistant to wear and corrosion, and when used in a leadpipe, it ensures long-term precision. | |
