L Gapper®

The Gapper® is designed to take up the gap between your finger and the 3rd valve slide ring. The size Gapper® each player prefers depends on a variety of factors: brand of instrument, taper of finger, etc. However, most players find that, with Bach instruments, the size of Gapper® corresponds with ring size in roughly the following way: 3XS - 3; 2XS - 4; XS - 5; S - 6; M - 7; ML - 8; L - 9; XL - 10. We also offer a size guarantee. Check our return and refund policy below.

Our goal is 100% customer satisfaction! Every Gapper® is checked before mailed to a customer. However, should something get damaged during the shipping process, contact us and we will replace your Gapper®. 

We also offer a size guarantee. If the Gapper® you purchased is the wrong size, let us know within 30 days by emailing info@trumpetgapper.com.
