Holton Trombone - TR160
“The Holton TR 160 is one of the best large bore tenor trombone I've played. I was not very familiar with the Holton trombones and had been playing a Bach 42B open wrap and then a 42T with a Thayer valve. The Holton 160 is quite flexible with a great focused tone and intonation. The range is very easy and even from pedals to the high range (some reviews comment on the high range, but I find it easier than on other horns). The F attachment is fast and matches the straight horn well. The slide is extremely smooth and fast, and is a little narrower than on the Bach. I find this helpful when switching between the Holton and the smaller bore Martin. The nickel silver slide is lighter than a standard Bach slide, but not as light as their light-weight slide. I wasn't sure if I would like the 9 inch bell, but it responds very well. The tone is full and rich without being too heavy. The Holton falls between a Conn 88H and a Bach 42B in sound and feel. It is a really wonderful trombone to play!"

What is an F attachment or "trigger" on a trombone?
The F attachment or "trigger" is a rotary valve added to the trombone, mostly found on larger bore models. This valve is operated with the thumb, and works like the fourth valve on a euphonium or tuba. When added to the slide, it drops the pitch to a lower harmonic series. For example, play a first position middle F, add the trigger, and you can now play a C below the F in first position. This increases the low range of the trombone and also offers additional alternate positions. There are many types of valve available for the F attachment, many with the goal of more closely matching the feel and sound of the "straight" trombone (one without a trigger). The rotary valve is the most common, with the Thayer, Hagmann, Greenhoe, Christian Lindberg, and Bach K valve available as well. The "open wrap" style of tubing is also a popular option, although some players still prefer the traditional (closed) wrap. The open wrap has fewer bends in the tubing, "opening" up the feel and sound of the trigger. Most major trombone brands offer both styles of wrap, and some offer a choice of valves.
