Since the discussion about Spiro Starks are pretty active at the moment and someone raised the question, if they are any good for solo playing (in orchestral tuning), I was thinking about a Stark version of the solo tuning set. A Spirocore Weich string tuned up a whole step should have the same tension as a Spirocore Stark string in orchestral tuning. Did someone ever try this? I have read somewhere, that Gary Karr used to use orchestral tuning A & E strings, tuned up a step as B & F# solo strings. If it works out, this could be a wonderful all purpose string, for orchestral playing, jazz playing and the possibility, to play solo repertoire in solo tuning, all on the same bass with the same set of strings. Perhaps one could lessen the pressure on the table, by installing an adjustable saddle.
