My low b is 135 and its really really really flabby. Any suggestions. I am ok with but will lighter gauge make it less flabby? I have been thinking of la bella hard rocking 5 string wiht high c. Anyone using 5 string with high c, please give some info like why u use them, problems, comparing with low b whats the diff!!! How does the overall bass feel change. Dont know. Tell me your whole experience. Thanx.
