Just returned from a holiday in Berlin and while there visited a great Museum dedicated to Musical Instruments. There were some amazing basses, cellos, gambas and other string instruments. I noticed several basses with an extra bit of gut string running between the bridge and the tailpiece. I have not seen this before and was curious if anyone new what the thinking was behind this setup? Was this common on early baroque era instruments? See attached pictures. Bass was labeled Andreas Jaiss, Tölz - 1730 I would highly recommend the museum as a must for a visit to Berlin.
