This thought crossed my mind tonight, and I was wondering if there are any prominent examples of it being used. Are there any bass players who string their solo bass B E A C? Or rather D instead of C in this case, keeping in line with the solo tuning? It just seems like it would be very advantageous for a lot of music, and especially transposed cello music. I undertstand the difficulties of playing with this different tuning (although technically this could be remedied by transposing the key and playing the bass as if it were still tuned normally, just as how solo tuning works), but couldn't this be very useful? Would this high string work, or would it end up being far too thin? I'm very interested on the subject, and may very well purchase a smaller bass to try this out. Even in "standard" tuning, A D G C, this would be very interesting. Anyways, just a thought, any feedback would be greatly appreciated.
