I have a Carvin J type bass with a bolt on neck. I bought it as my "round wound" bass and it works great with rounds but I'm just NOT a fan of rounds. The only problem with switching to flats is that this particular bass has a very thin neck and I worry about stressing it with high tension strings. So T.B. What flats offer lower tension and a BIT brighter tone than my P-bass with Deep talking flats?
