What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Cut for contra-bass mouthpiece diameter only. A bass clarinet ligature is a different size and the two don't cross over.
Detail 02
Rovner's Dark line, so expect a rounder, less edgy response than the brighter ligature options in their range.
Detail 03
You get the mouthpiece cap matched to the ligature, so the reed stays protected in the case without buying a second part.
Detail 04
One screw sets the clamping pressure, which makes swapping reeds fast but gives less independent adjustment than two-screw designs.
Detail 05
Cheap relative to a contra mouthpiece, so it's a low-risk change if your current ligature slips or dents reeds.

Product questions

Yes. The ligature and its matching mouthpiece cap are both included.
The Dark line leans toward a rounder, less edgy response. How much you notice depends on your mouthpiece and reed pairing.
Yes. Synthetic reeds don't swell like cane, so you may need slightly different screw tension than you're used to.
