Overview
This Olds O-25 Large Bore Tenor Trombone, serial number 817487, was made in the early 1970s and represents a strong example of classic American brass craftsmanship. Featuring an 8.5" gold brass bell, nickel silver handslide, nickel silver valve wrap and tuning slide, and a traditional rotor, this model delivers the durability and tonal richness Olds was known for during this era.
This is the same instrument previously sold by The Brass Exchange and now returned to market, continuing to present as a well-preserved and musically rewarding vintage tenor. Instruments with known history and consistent care often stand out, and this example reflects that continuity.
The overall condition remains very good, with original lacquer intact and only normal signs of careful use. The instrument offers a rich, warm tonal profile with excellent projection, making it a compelling option for players seeking a vintage symphonic tenor without stepping into the higher price tiers of modern boutique instruments.
Now included is a lightly used S.E. Shires Q30 case, providing a modern, protective solution for transport and storage.
Player Perspective
The Olds O-25 sits in a unique space among vintage American large bore tenors. It shares some design influence with the George Roberts P-22 bass trombone, particularly in its robust construction and tonal depth, while remaining firmly in the tenor category.
In play, this instrument delivers a broad, dark sound with strong core and projection. It responds well in symphonic settings while still maintaining enough flexibility for varied ensemble use. The traditional rotor offers a familiar and reliable feel, and the large shank receiver allows for a wide range of mouthpiece pairing options.
Compared to many modern instruments, the O-25 can feel substantial in hand, but that weight contributes to its tonal stability and presence. For players who appreciate vintage American horns, this model offers a distinct voice that stands apart from contemporary designs.
