Plunger design
Held in the off hand and worked over the bell. Nothing seats in the horn, so intonation stays close to open.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Held in the off hand and worked over the bell. Nothing seats in the horn, so intonation stays close to open.
Detail 02
Wider than a tenor plunger to cover the larger bell. On a tenor horn it will be oversized and hard to control.
Detail 03
Humes & Berg's construction line; the lining shapes a darker tone than a bare rubber plunger cup.
Detail 04
Both hands are occupied while playing, so you cannot work the slide and the plunger at the same time as freely.
Detail 05
Entry pricing for a bass trombone specific plunger, which is a harder size to find than tenor.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is cut for bass trombone bells. On a tenor it will be oversized and awkward to control, though it will still cover the bell.
No. A plunger is held in your hand over the bell and never inserts into the horn.
Far less than a straight or cup mute, since nothing seats inside the bell. Pitch shifts as you close it, which is part of the effect.
It is built as a mute rather than a tool, with the Stonelined interior giving a darker tone and no rubber odor.
