GR 66 S-B Trumpet Mouthpiece

Excellent condition with minor insertion marks.

Information from the manufacturer:

The GR 66 Series cup diameter is similar to a conventional 3 diameter.

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.

S-B and M-B Cups The Ultimate High Compression Mouthpiece For Players Who Can't Play Shallow Cups!

• In an effort to please players who have a tough time with the standard GR high compression Z cups, and for those who have a tendency to bottom out on the GR S cups, Gary Radtke has developed the S-B Series Trumpet Mouthpieces.

S-B Cup

• For those of you who can not tolerate a shallower cup and higher alpha angle, these are the ultimate lead and commercial mouthpieces.
• The GR S-B Series Trumpet Mouthpieces are designed using the GR design program so each model will feature that fat GR sound.
• 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."
