This is a Conn 88HO professional model tenor trombone featuring the open wrap F-attachment, one of Conn’s most popular and enduring designs. The instrument is in excellent condition with no history of major damage or repairs. It retains its original lacquer, which shows only minimal wear, making this a standout example of a modern classic.
We performed a full shop service, including chemical bath, rotor servicing, and full slide adjustment. The slide is responsive and aligned for maximum playability. The valve section is smooth and quiet, making transitions easy and efficient in both legato and articulated playing styles.
Specs include an 8.5" rose brass bell, a standard weight .547 bore handslide, and a large shank mouthpiece receiver. The rose brass bell adds warmth and depth to the tone — a notable contrast to yellow brass, especially in large ensemble settings. This instrument is an excellent choice for symphonic work, concert band, or advanced all-around playing.
The Conn 88HO remains one of the most recommended professional trombones by band directors and private instructors across the U.S. The same model new today sells for over $3,400 — a strong value for players seeking performance and savings in one package.
What’s the difference between the Conn 88HO and the traditional 88H?
The primary difference lies in the valve section design. The 88HO features an open wrap, which offers a more free-blowing response and reduced resistance when the F-attachment is engaged. Many players feel this helps with smoother transitions and improved flexibility. Both share the same bore size, bell material, and overall layout — but the open wrap gives the 88HO a more modern feel and tone projection, especially in symphonic settings.
