Here's my situation. I have a plywood bass that currently has spirocores on it. As I've heard, these are pizz oriented strings, I'm in desperate need of arco strings, and I don't care very much for the sound of these bowed. I'm the only bass in our school's small orchestra, which actually has no cellos. 6 violins, 3 or 4 violas. I need a sound that would fill that low gap, so something loud and bassy. I'd like to have a sound that bridges the gap between solo and orchestral strings, but they need to be in orchestral tuning, since I'm going to be getting ready for college auditions. So kind of a mix between a really nice set of orchestral strings and something you'd here on a recording of a Bottesini solo. That's kind of what I'm looking for, is there a string that can fill this, or am I better off just getting a good set of orchestra strings? Price is not a concern, can anyone help me out?
