This Conn 88HO large bore tenor trombone was a single-owner instrument, played for less than a year and kept in super-mint condition.
It shows only minimal signs of use and delivers the classic, broad Conn tone that has made the 88H series a mainstay for orchestral and solo trombonists since the 1950s.
This example features a red brass 8.5" bell paired with the “O” open-wrap F-attachment, which offers smoother airflow and a freer-blowing feel when using the valve section.
The slide was in excellent condition, contributing to the horn’s quick response and comfortable playability.
Prior to sale, it underwent a full professional service, including a chemical bath and flush, slide adjustment, and valve inspection, ensuring that the instrument was ready to play out of the box.
The package also included the original Conn case, a trombone care kit, and a mouthpiece.
The Conn 88H series, first introduced in the 1950s, became an industry standard for large-bore tenor trombones, thanks to its warm, projecting sound and reliable design.
The 88HO variant adds an open-wrap valve section, an evolution that many modern players prefer for its freer blow and smoother valve transitions.
Although originally intended as a feature to reduce moisture buildup, the open-wrap design also changed the response in a way that appeals to many players.
As of 2025, a new Conn 88HO sells for over $3,400, making well-maintained, pre-owned examples like this one an attractive option for serious players.

❓ FAQ
What makes the Conn 88H series so legendary?
Since its introduction in the 1950s, the 88H’s broad, warm tone and reliable large-bore design have made it a favorite for professional orchestral players and advanced students.
It has been widely adopted in symphonies, studios, and academic programs for decades.
What is the difference between the 88HO and the standard 88H?
The key difference is the open-wrap F-attachment on the 88HO.
While often promoted as “more open-blowing,” its original purpose was to reduce condensation buildup in the valve tubing.
Many modern players enjoy the slightly freer response and smoother valve transitions it offers, but seasoned pros often find either design performs equally well once they adapt.
Is an older Conn 88HO still a good choice compared to a new one?
Absolutely.
Many players value earlier production examples for their bell resonance and slide craftsmanship, often preferring them to newer models.
A well-maintained vintage 88HO can still deliver top-tier performance for orchestral, solo, or commercial work.
Why do players sometimes prefer red brass bells?
A red brass bell generally offers a warmer, darker tonal core compared to yellow brass, with a touch of added richness in the mid-range — a quality many players favor for orchestral and symphonic repertoire.
