Marking a noticeable advancement from the '600' series, the new and enhanced range of JP brass mouthpieces offers a higher standard of build quality and precision. The silverplating quality has been significantly improved, making these mouthpieces a noticeable step up. Designed for advancing players, these mouthpieces serve as an affordable option for those seeking to upgrade.

The John Packer 6.5AL large shank mouthpiece features a medium-deep cup and a 25.40mm inner diameter, providing a rich tone and facilitating easy high register playability. Distinct from the 6AL model, this version has a slightly shallower cup.

Please be aware that this mouthpiece is suitable for large bore trombones and euphoniums with a large mouthpiece receiver.
