A free-blowing trombone with a tone as expansive as its range.

The Conn 88HO Symphony Series F-Attachment Trombone delivers a playing experience as open as its wrap. Its .547" primary bore and .562" wrap bore facilitate effortless airflow for musicians at any level. An open-wrap F-attachment design provides extended range and alternate positions with minimal resistance. The 88HO projects your sound with an 8.5" rose brass bell, imparting a tone with depth, warmth and clarity that fills even the largest concert halls. A standard rotor valve and mechanical linkage enable lightning-fast triggering across the trombone's full range. Whether you're performing a solo or blending with an ensemble, the 88HO's responsive action and balanced articulation make it a natural choice for any symphonic musician.

Open-Wrap F-Attachment Provides Extended Range
The 88HO's open-wrap F-attachment enhances playability by eliminating airflow resistance. Its dual-bore design, with a 0.547" primary bore and 0.562" wrap bore, enables effortless transitions between open and wrapped positions. The open wrap facilitates slurs, trills and fast slide work while expanding your range down to pedal Bb. For symphonic musicians, the 88HO's open wrap offers more creative freedom by providing alternate positions and an array of color options.

Rose Brass Bell Resonates with Depth and Clarity
At the heart of the 88HO's tone is an 8.5" rose brass bell. Rose brass, with its high copper content, produces a resonant, complex sound with rich overtones. The 88HO's rose brass bell generates a tone that is deep yet vibrant, with note definition that cuts through even the densest orchestrations. Its tapered shape directs sound outward, allowing you to project to the back of any concert hall. For ensemble or solo use, the 88HO's rose brass bell provides a balanced, nuanced tone that complements any musical style.

Responsive Rotor Valve and Tuning Slide
The 88HO features a standard rotor valve with a mechanical ball linkage for fast, accurate triggering. Its lightweight, durable design enables effortless transitions between open and wrapped positions. A yellow brass tuning slide provides stability and resonance while facilitating quick adjustments on the fly. For live performance, the 88HO's responsive valve and tuning slide give you full control over pitch and articulation.

Durable Lacquer Finish
A stylish lacquer finish protects the 88HO's rose brass and yellow brass components from tarnish and wear. Lacquer is easy to maintain, requiring only occasional polishing to retain its mirror-like sheen. Its durable, chip-resistant surface keeps your 88HO looking like new for years to come.
