Why the F-Trigger Attachment?
There are two advantages to using a tenor trombone with the F trigger attachment: one is musical and the other is operational.

History of the F-Attachment
Trigger trombones are a mechanical modification of the straight slide trombone. The modern trombone evolved from a 15th century Englinsh instrument called a sackbut which looked very similar to a straight tenor trombone.

Open Wrap v. Closed Wrap
A closed wrap, sometimes referred to as traditional wrap, keeps all the extra tubing of the F-attachment confined within the bell section of the trombone. An open wrap allows the tubing to extend beyond the crook of the bell section.

String or Mechanical?
There are two types of linkage that open and close the valve on an F attachment: string or mechanical.

Types of Valves
The most common type of valve on a thumb operated trigger trombone is the rotary valve. A rotary valve was used on the first ever trigger trombone developed by Christian Friedrich Sattler in 1839. It has a good ergonomic design and a short throw.

Materials
Like all brass instruments, a trigger trombone is made from brass (surprise!). Because brass tarnishes easily, it is finished with a lacquer or some other material such as silver or gold plating. Whatever the instrument looks like on the surface, it is almost always brass underneath.
 
Mouthpieces
The mouthpiece is arguably the most important part of your instrument.It is where you and your instrument connect.

Buying Online
There is one disadvantage to buying a musical instrument online: it is not like walking into a store and being able to try out several instruments at once. However, there are significant advantages to buying your trigger trombone online.
