✦ Historical Perspective
The Rath R3 is part of the early generation of Michael Rath custom trombones, hand-built in England and designed for players seeking the flexibility of a medium-bore instrument combined with the precision of modern custom construction.
This particular example features a .525 bore handslide paired with an 8" yellow brass bell (750Y), producing a sound that sits comfortably between small-bore jazz horns and larger symphonic tenors. The nickel silver slide offers quick response and clarity, while the yellow brass bell provides warmth and projection.
A defining feature of many Rath instruments is the use of removable leadpipes, allowing players to adjust resistance and response depending on mouthpiece choice or musical setting. This instrument includes three interchangeable leadpipes, two configured for large shank mouthpieces and one for small shank, offering additional versatility for players moving between jazz and concert band environments.
The instrument also features the signature Rath tuning slide balance weight, integrated into the tuning slide assembly. This design helps stabilize the instrument and improves balance in the hand.
Overall condition on this example was excellent. Minor dings previously present on the tuning slide crook were professionally removed, and the instrument maintained strong original lacquer and outstanding slide performance. The handslide was smooth, responsive, and tension-free.
This Rath R3 delivered a complex, flexible tonal character and served as an excellent example of the craftsmanship associated with Michael Rath’s English workshop.
Questions Trombone Players Often Ask
What is a Rath R3 trombone?
The Rath R3 is a professional medium-bore tenor trombone with a .525 slide, designed to bridge the gap between small-bore jazz instruments and large-bore orchestral trombones. Many players use the R3 for commercial work, jazz ensembles, chamber music, and concert band settings where flexibility is important.
Why do some Rath trombones have removable leadpipes?
Removable leadpipes allow players to adjust how the instrument responds. Different leadpipes can slightly change resistance, articulation clarity, and slotting. Many professional trombonists use this system to fine-tune how the instrument works with their mouthpiece and playing style.
Is a .525 medium-bore trombone versatile?
Yes. The .525 bore size is often considered one of the most versatile trombone designs. It provides more breadth and depth than a small-bore jazz trombone while remaining more agile and responsive than a large .547 orchestral instrument.
