The 114XD is our largest, deepest bass trombone mouthpiece. It is the best choice for a player using the Bach 1G, Schilke 60, or similar mouthpiece, and who does not have significant problems with range and endurance.
- ID: 1.14 inches
- Throat: .320 inches.
- Note - Some bass trombones, for example some vintage King models, have an extra deep receiver. If your mouthpiece inserts more than 1.25 inches (31 mm) into your leadpipe be sure to select the BT Deep Receiver option when ordering bass trombone mouthpieces.
