Optimal Pressure System for Trumpet
- Fits all Warburton trumpet tops
- Works like a normal back-bore
- Too much pressure releases the air
- Helps with “pressure-weak” practice
- To adjust the pressure: Unscrew the appliance and change the tension of the spring by removing the rings
- Does not extend the instrument, so you can O.P.S. also in the music sample use
Note: Warburton top is not included.
