Greenline tenon protection Greenline instruments are made out of a blackwood/Mpingo composite wood which prevents the instrument from cracking. Greenline instruments are just as professional and refined as wooden instruments. Unfortunately, they come with one weakness, the tenon can break when exposed to a fall or hard hit.

Lohff & Pfeiffer offers special tenon reinforcement that prevents breaks when the instrument is dropped or hit.
