Who this is for

- Players moving from a small shank setup to symphonic gear

Consider the trade-offs

- Beginners still building embouchure strength
What matters in use
The specifications, translated
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 02
5G rim size
Mid-size diameter in the G family. Enough rim for endurance without the stretch of the widest models.
Detail 03
G cup designation
Deeper cup than standard tenor mouthpieces. More core and low-end volume, more air required.
Detail 04
Bach model numbering
Lower number means wider rim. A 5G is narrower than a 1-1/2G, wider than a 7C.
Detail 05
$85 price
Standard professional mouthpiece pricing. Most players own several and swap by playing situation.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if your trombone has a large shank receiver, typical of large bore tenor and bass trombones. Small and medium bore horns use small shank mouthpieces and will not accept this.
02What is the difference between 5G and 5GS?
The G designation covers cup depth. Suffix variants change the cup or throat further. This is the standard 5G with no additional suffix.
03Is this good for jazz or lead playing?
The deeper G cup favors orchestral and section work over lead. Commercial players usually want a shallower cup for range and brightness.
04Is it too big for a student?
It requires more air than a student-size cup. A player still building embouchure strength will tire faster on it.
