A light, knock tolerant plastic alto trombone that lets young beginners and trumpet doublers play real slide notes. It is an alto in Eb with a small shank mouthpiece, so it does not stand in for a full size tenor.

Overview
A young beginner or a trumpet player who teaches gets a fully working alto trombone made from ABS and glass fiber. The slide locks, a water key clears moisture, and the small mouthpiece lets children reach a wide range of notes.
Light weight and a body that shrugs off bumps let children explore the slide without a list of warnings. Its pitch and small shank set it apart from a standard tenor, so it suits starting out and teaching more than ensemble seating.
Who it's for
Families with a young starter and brass teachers who demonstrate on the slide get a light instrument that tolerates knocks. Players who need a tenor's pitch or a standard mouthpiece fit should choose a brass horn.
Pros and cons
- Under half the weight of brass alto
- ABS and glass fiber resists knocks
- Lockable slide with clear graphic
- Water key built in
- Eb alto, not a tenor trombone
- Small shank limits mouthpiece swaps
- Warranty details not listed
Performance notes
Pitch and range come from the dual bore slide and the narrow mouthpiece, which makes higher notes easier for small players. Composite slide tubes lap in over time, so the action grows smoother the more it is played.

Frequently asked questions
How do I put the pBone mini together?
The listing gives no step by step assembly. It does note a lockable slide with a graphic that makes the locking process clear, and a small shank mouthpiece.
Will a standard trombone mouthpiece fit the pBone mini?
The pBone mini uses a small shank, and its own mouthpiece is smaller in diameter than any other trombone mouthpiece the maker knows. Check the shank size before swapping.
Can a trumpet player use the pBone mini?
Yes. pBone says its small mouthpiece suits trumpet players who want to double on it for teaching.
Does the pBone mini slide get better with use?
Yes. The composite slide tubes lap in over time, so the slide improves as it is played.
