A double bass with six strings?!? No, a violone. This instrument, which belongs to the viola da gamba family, looks quite similar to a double bass, but the body is slightly larger than that of a ½ bass, while the scale length is slightly smaller at 90 cm.
This G violone was built in 1962 by luthier Uebel in Celle/Germany. The tuning pegs are mounted in such a way that the direction of rotation of the pegs is the opposite of what you would expect from a bass. This means that you have to turn “downwards” to tune up. At first, I thought this was a mistake… something that can happen even to the most skilled instrument maker. However, I now assume that the tuning pegs were deliberately mounted this way so that the gut strings could be threaded over the pegs from below, rather than from above as is usually the case. This makes the angle at which the strings run over the nut slightly more acute, and the relatively thin and soft gut strings lie with a little pressure on the nut. The fairly wide notches in the original saddle indicate to me that the strings were previously strung in this way.
