Can anyone recommend a good resonant steel string to use as a low C string? A few months back I started to switch to 5th tuning (A, D, G and low C open strings). I've had to re-string my bass and now have Original Steel Chrome on all strings, solo A, orchestral D, solo F# tuned up to G, and a solo C# tuned down to C. I play a lot of orchestral music, but also shows and jazz for which I use a magnetic Krivo pick-up, so I need steel strings. The A D and G are OK. The C# string is OK for arco, but does not ring at all, just a dead thud. So I need a more resonant steel string to use for low C. Anyone got any suggestions?
