Holds your reed. Never touches your mouthpiece.
Four cords of aerospace-grade cordage in a silver twin-beam frame — the same high-tensile class trusted on NASA Mars landing systems.
- Zero-stretch cord that molds to your mouthpiece over time
- No metal on the mouthpiece — your tone stays your tone
- Butterfly nut locks tension with easy turns
- Silver finish · 4 cords · 2 fine tuners · 1-year warranty
Before any ligature existed, players simply tied a cord around the mouthpiece and reed.
It wasn’t a compromise — it was the sound. The H4S is that idea, rebuilt with cord engineered for space.
Cord tested by Mars
High-tensile cordage from aerospace exploration, including NASA’s Mars rover landing systems. Zero stretch, so your tension holds through a three-hour rehearsal and doesn’t creep between reed changes.
It learns your mouthpiece
With use, the cord memorizes your mouthpiece’s exact contour — settling into the shape that mounts fastest and sounds best. It gets better the longer you play it.
Zero added mass
Only the cord touches the mouthpiece — never the metal frame. With no metal mass added, your mouthpiece keeps the exact resonance its maker designed.
Three-layer coating
A coating developed on top of the space cord, for four gains:
- Absorbs no sound energy — nothing of your tone is lost to the cord
- Glides on the mouthpiece surface without marking it
- Stronger than steel cord, with zero stretch or breakage
- Lasts decades, and cleans with ordinary kitchen soap
How it plays
In playing tests, the four-cord H Frame came back balanced, free-blowing, open, and highly resonant — the greatest sense of reed freedom of any configuration tested, and very even across all registers.
Warranty: 12 Months
