I currently have 4 trombones:
1. My Numero uno is an Edwards T350 tenor trombone with an f attachment (axial flow valve) and an open wrap. It has a
rose brass bell and a dual bore slide (.525/.547). I use it mostly for concert band.
2. The second is a Bach Stradivarious model 36. It is a .525 bore, yellow brass with a conventional valve for the f attachment.
I have been using it to play in the German Oompah band.
3. A King model 3BF(.508 bore). It has a yellow brass bell, a conventional valve and conventional wrap f attachment.
I use it when I play in a dixieland or stage band.
4. This one is a straight tenor, gold plated 100 year old Martin. It has been retired for several years.
