Product questions
Straight answers to the questions shoppers most often ask about this product.
Stem in and cupped with your hand gives the wah effect. Stem pulled out gives the thin, buzzy stemless sound heard on classic jazz recordings.
Yes. Copper reads warmer and slightly darker. Aluminum is brighter and more cutting. Both keep the Harmon focus.
It's cut for standard trumpet bells. Bell throats vary between makes, so check the cork sits firmly without being forced.
Not really. It reduces volume some, but the point is tone. A dedicated practice mute cuts far more sound.
