Product Overview
The 108G is very similar to the Bach 1.25G and 1.5G, with a nearly identical cup, when you allow for the Wedge oval shape. The Bach 1.25G and 1.5G have very similar cups, with the main difference in the two mouthpieces being the softer bite radius of the 1.25 rim, which makes it feel bigger.
The updated G3 design is similar to the Gen 2 line, but the top and bottom rim of the G3 each have a slightly different shape. The bite on the rim is also slightly softer. Most players prefer the wider rim at the top and the orientation dot at the bottom, but the mouthpiece can be pllayed in either orientation.
- ID: 1.08 inches, measured at .05 inches into the cup.
- Throat: .300 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.
