I don't currently represent GR mouthpieces, but I have a few in stock.
For Bb trumpet:
- e62M - wide rim, less bite, 0.62" diameter, medium cup
- 3HC** - flatter rim, soft bite, C cup, open throat

Standard GR Rim
- The Standard GR Rim is composed of medium characteristics.
- This rim is comfortable and is generally easy for most players to adapt to quickly.
- The width may feel a bit more generous than traditional rims and will aid endurance.
- Flexibility is good and articulations will be cleanly defined.
- This is our most popular rim choice and ""blind"" tests have proven that it is favoured over many conventional rims.
- Standard Rims have no designation on the mouthpiece itself.
- The GR e - Rim is made for those that require a wider feel and less bite.
This rim is ideal for players that require good endurance; furthermore, it is great for downsizing giving the player the same OD yet smaller ID.
- The bite is medium soft and contour is semi-flat.
E Rims have an ""e"" designation on the mouthpiece.
- This rim is standard on the e62 and e65 Series Mouthpieces and is available on other models as a special order.
Note * If a rim is too flat or too wide it will impinge lip vibration and cause a thin sound on certain players. On the other hand many players can benefit from added support with this type of rim.
- The GR G Rim was originally designed by Gary Radtke for his own use but with it's popularity, we decided to add it to our line.
- The G Rim has the same bite contour as our Standard rim but the rim is slightly wider and outside radius is slightly larger.
- This gives the player more effective rim area on the chops as mouthpiece pressure is applied.
- It aids in the distribution of pressure over a larger lip surface which will give support and aid endurance.
- This rim does not feel overly wide and flexibilities will not be compromised.
The G Rim will have a ""G"" designation on the mouthpiece.
- This rim is standard on the G66 Series Mouthpieces as well as some G67 models, and is available on other models as a special order.
3 Series Rim

- It may have a familiar feel to conventional 3 players but with GR improvements in comfort and articulations.
- All 3 Series Mouthpieces have the same alpha angle.
The bite is softer than the Standard GR Rim and GR E-Rim.
- The larger bite radius may make the rim feel larger.
The outside diameter is slightly narrower than the Standard GR Rim.
- This is a generous rim with excellent grip and support.
- This popular rim is flatter than the GR E-Rim and will feel more cushioned than the Standard GR Rim, yet with increased grip.
- The Z* rim offers secure comfort, endurance and distribution of pressure.
- The bite is medium and the alpha is high.
- This is a very popular choice for players using conventional ""4"" rims who need increased endurance with improved articulations.
- Same as the Z* Series rim with a softer bite.
- This allows for slightly more chop in the cup and is an excellent choice for commercial players who are accustomed to a softer bite.
- The Z** rim offers secure comfort, endurance and an even distribution of pressure.
- This is an ideal rim for players used to the Schilke 4 rim feel.
64.7 Series Rim
- This rim is slightly wider than the GR Standard Rim and features a comfortable semi - flat contour.

- This rim is excellent for a player that doesn't get a vibrant sound on a flatter rim or with a sharp bite.
- The rounded contour and soft bite makes this rim feel larger with added support.
- Flexibility is excellent, articulations snap.
Q Series Rims
- The Q rim is slightly flat, outside diameter follows is tradition in width and contour, highpoint is further out than the standard GR Rim.
- The bite is medium sharp with the traditional feel and grip, and the alpha is medium for lip freedom, support, and articulation.
- The bite grip holds the lips from penetrating too far into the cup.

The Z Cup has a small cup volume that features a brilliant fat and powerful sound throughout the horn and an astonishingly easy upper register.

Try this mouthpiece if you are playing a GR 64Z* and you bottom out or feel like you shut off. Also, if you play a Wick 5E and want improved articulation, sound, projection, and intonation with a similar feel, look at the 64E-5. If you play a Schilke 10A4a and you bottom out or feel like you shut off, this piece may be an ideal alternative.
- The SZ Cups feature the standard GR-Rim and alpha of the Standard GR Compu-Balanced S cup.
- The SZ cup basically has the rim and alpha of the S cup and the bottom of the Z with the GR #1 Backbore.

- The SZ cup is outstanding for lead work, marching band/drum corps, Latin, jazz, and studio work, great for microphone work and records well.
- Recommended for players who feel the Z cup impinges the lips, not enough lip room, has an alpha angle that it too high, or the rim is too flat, as well as, a great choice if the S cup doesn’t provide enough compression for range requirements and articulation or enough edge to the sound.
