I ordered this Heydays system. It is excellent, but ONLY for smaller and medium bore trombones, but for my large-bore (.547) instrument, the brush/mop set is too small!
Internet research revealed that Heydays produce a SPECIFIC SET OF BRUSHES/MOPS for large-bore trombones.
This is not made clear at all by the Thomann website info. Perhaps you guys could please start stocking the large-bore brushes as well, and make it VERY clear that these brushes are UNSUITABLE for large-bore trombones? Thank you.
