This product data sheet is originally written in English.


This is a Professional Grade Bass Trombone
It plays just like the Conn 62 independent valve, and Holton horns it was designed from. The open wrap design blows evenly and comfortably in all registers, and features a warm yet commanding tone. This is a free blowing horn that is a joy to play!
Special features of the O'Malley Professional Bass Trombone:

Hand Lapped Valves and Tuning Slides:

Open wrap tubing design

Inner slide - The inner slide is very durable and has a quick, sensitive response.

I swapped one of these horns on a very distinguished bass trombone player and he was knocked out with the sound and came off of his pedestal about the origin. Besides, many of the name brands all have horns made in the far East!
Outer slide - The one-piece, drawn, yellow brass outer slide maintains an accurate diameter throughout its length, and this type of construction ensures smooth action, exceptional durability, and great response.
Inner slide stockings - Specially designed, one-piece, inner slide stockings guarantee airtight slide construction, and offer smoother slide action and better alignment.
Hand-lapped valves and tuning slides - Hand-lapping slides and valves ensures an absolutely perfect fit and seal between the slide parts.
Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.
