GR 67 Rim Compu-Bal Trumpet Mouthpiece

Overview
Features

Quick Comparison - The GR 67 Series cup diameter is similar to a conventional 1 1/2 to 1 1/4 diameter. The 67L is a very popular choice for 1 1/2C players looking for more core in their sound with more secure articulations in a more efficient design.

67 Series: .670"/17mm

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.

MS -     
The MS Cup has a slightly lower alpha angle, greater cup volume, a slight increase in cup depth, as well as, a larger backbore than the S Cup. The MS has the GR #2 backbore as standard. The added volume and a slightly lower alpha angle than the S Cup gives the player more lip room.
"An ideal solution for players who find that the GR S cup is a bit tight for them. The sound is big and full with an excellent core. It has less edge than the S Cup and works well in all playing situations."

M -
The M Cup has the same backbore as the MS Cup, the GR #2 backbore. The M Cup has a slightly lower alpha angle, more volume and more depth than the MS Cup, although, the playing characteristics are similar.
"An ideal all around mouthpiece with a compact core, vibrant feel, and full of overtones. This is the most popular GR Cup."

MX -
More volume and more cup depth, lower alpha angle than the M Cup, and the larger GR #3 Backbore.
"This cup is popular for larger less resistant horns and also for lighter chamber work. The MX Cup projects well throughout the Concert Hall with a brillaint tone and is very even throughout all registers. If you are looking for a cup that is fat, precise, and brilliant, the MX cup is an ideal choice."

MB -
M-B has more upper cup volume than the M but it is tighter in the bottom of the cup and throat entrance. Even though the M-B and M cups have virtually the same volume, the M-B is not as deep as the M cup.
"The M-B was designed for those who want an all around mouthpiece with more chop room than the GR M cup, plus a slightly brighter sound and faster response than the M."

SB -
#1 Backbore, GR Classic Blank. Medium alpha angle for added chop room. "High Compression" throat entrance. Balanced throat length and diameter.
"For those of you who can not tolerate a shallower cup and higher alpha angle, these are the ultimate lead and commercial mouthpieces. Crisp articulations, full low register, amazingly easy upper register are some of the benefits of the S-B design. The S-B Series is specifically designed for players who require the additional chop room to prevent bottoming out."

VB -
The VB cup has the same parameters as the VC for the rim and upper cup. The throat entrance and bore are tighter and this mouthpiece doesn't require as much work.
"This works well on the Bb for concert band to jazz work. It is also good the C trumpet."

L -
The L Cup has a lower alpha angle, increased depth, slightly more volume than the MX Cup, and a #3 Backbore.
"The sound presence is around you where the MX cup projects with a sound that is more direct. This cup plays very evenly throughout the registers and the sound is rich with resonant overtones. Preferred for Concert Band, Wind Ensemble, Brass Quintet, Chamber Work, Orchestral Work, Solo Work, and Jazz."

LX -
The LX Cup has a very large cup volume, increased depth, an alpha angle much lower than the L Cup, and a #3 Backbore. This allows for a lot of lip engagement into the mouthpiece.
"An outstanding orchestral and solo mouthpiece, used by top orchestral players the world over."

C* -
Feature the GR Classic Blank, GR Standard Rim, and GR #3 Backbore.The C* was designed for all-around Bb use featuring a higher alpha angle (similar to M cup) and a larger cup volume.
"The C* has an improved throat entrance over older "conventional" C cup designs which allows improved articulation, accuracy, and efficiency, along with a pure core of sound not found on most traditional mouthpieces. A beautiful full sound with excellent projection, as well as, the ability to blend in any situation."

C** -
Feature the GR Symphonic Blank, GR Standard Rims, and GR #3 Backbore.  
"The C** was designed to have a similar blow and feel to older traditional C cup designs, although, improving intonation, slotting, articulation and efficiency. It is an excellent choice for the Bb and C trumpet featuring a higher alpha angle (similar to M cup) and a larger cup volume. The C** has a more open throat entrance than the C*. A powerful mouthpiece that has a great volume of sound, good articulation, and excellent projection. Great choice for the orchestra, concert band, solo work, or quintet."

CT-Z -
While retaining a similar feel as the B-T and C-T cups, the CT-Z is a high compression cup designed for players who are used to a wider diameter mouthpiece.

"This versatile cup is ideal for pops or commercial work but is designed with a lot of lip room for players who use chop engagement. Scream all night without bottoming out!"
