LefreQue 55 mm Band for medium-sized connections
The lefreQue is a sound bridge that will make all wind instruments sound better. It consists of a bridge that is built up by two metal elements that will repair the sound breaches that occur in different parts of a wind instrument. You can put the lefreQue on your instrument using an especially developed elastic band. You do not need to change anything on the instrument itself.
This elastic band connects the lefreQue between the medium-sized joints.
