In 1903, German bass maker Otto Roth (1876-1954, Vogtland area/Bohemia) finished a huge double bass with almost 4.20 m height and 2.10 m body length. The photo (taken in 1905) shows the enormous size of this “moster” bass: twice as big as a regular bass. For getting it out of the workshop, the window has been the only way out. Roth made this bass for the Chicago opera, but unfurtunately, no further informations about the use and ownership of this monster bass are available.(from the german instrument making magazine “Instrumentenbau” 1-2/2011)
