One Rim. Multiple Sound Concepts.

The CHI Brass Arnold Jacobs Adjustable Cup provides performers with unprecedented flexibility by allowing multiple cup configurations to be paired with a familiar rim. Modeled after one of Arnold Jacobs own stage used mouthpieces, this innovative mouthpiece allows musicians to adapt their equipment to changing performance demands without the need to carry multiple mouthpieces around with them. The only alteration we have made from the original is modern machining equipment for a tighter tolerance. Each one is hand made using the latest tools by a master craftsman.

Whether moving between solo, chamber, band, or orchestral settings, the Arnold Jacobs Adjustable Cup Mouthpiece makes experimentation simple and practical.

Why Adjustable Cups?

Many performers carry multiple mouthpieces to accommodate different instruments and musical situations. The Arnold Jacobs Adjustable Cup allows musicians to maintain a familiar rim feel while exploring different cup depths and playing characteristics.

This can improve consistency while reducing adaptation time between setups.
