Any good anagrams for bass trumpet?

The bass trumpet is a type of low trumpet which was first developed during the 1820s in Germany. It is usually pitched in 8' C or 9' B♭ today, but is sometimes built in E♭ and is treated as a transposing instrument sounding either an octave, a sixth or a ninth lower than written, depending on the pitch of the instrument. Having valves and the same tubing length, the bass trumpet is quite similar to the valve trombone, although the bass trumpet has a harder, more metallic tone. Certain modern manufacturers offering 'valve trombones' and 'bass trumpets' use the same tubing, valves, and bell, in different configurations - in these cases the bass trumpet is virtually identical to the valve trombone.
