Hi all, I've got a couple of vintage basses that I'd like to restring with something new. I'm a round-wound type of guy and I've found that flats or rounds with the edges "flattened" lose the growl that I like. I used to like RotoSounds but they really gave the frets some grief. Then I found D'Addario's Slo-Wounds but since they don't make them any more... I'm looking for a string that will still give me the brightness and growl lacking in flats but aren't so hard that they destroy the frets on my '60 Gibson EBO, '66 Ric 4005, '69 Fender Tele Bass and '78 Ric 4002. Is there anything that you could recommend that will still sound great but won't destroy the frets. FYI, I've just picked up a set up Elixers to try but I'm certainly open to additional suggestions. Thanks!
