The "Jansen" machine was again designed around twenty years ago by Gallery Strings, but un-like the first two machines this one must use the screws and washers provided to hold the cog in place. The gothic design really suits very fine instruments and gives a very grand appearance. It has been used by many of the Worlds great bass makers, and we have never had any complaints about the design or fitting. In fact we have never had any complaints at all. This wonderful machine is named after the fine Dutch maker "Harry Jansen", my very good friend. Though the cog is a very obvious English design, it again, like the two earlier machines is very low geared for fine tuning.
