I'm going to try to be a specific as I can. I play in a rock band, so I need defined, aggressive sound thats not harsh. I can't stand harsh strings and I use a GK amp, so the bright harsh sound gets amplified (sometimes unbearably). BUT, I also need to strings to soften into a more jazzy mellow sound that sits in the mix nicely(not punching through everything else). I play 5 string, so the low B must sound defined. Doesn't have to be a huge fat sound, but I want no muddiness. Is this impossible? What's your best suggestions? Oh, and I would prefer a roundwound string. Flatwound strings feel slow and wierd to me.
