Maybe a bit of a contradiction in the title...? Anyway. I have a pre-CBS P ('64, early refin) with ten-year old GHS flats on it. The strings and the bass make a totally wonderful match with all the old school thump I could ever need. But. I can't help but want to try the bass with a set of nice rounds (I've had it for about a year). What would be a good set to check out for a big, warm rounds sound - on the "vintage" side? I use Rotosounds on my jazz bass (with Model J:s) and I get a great rock tone, but a bit more modern sounding. Looking for something a bit warmer. Thinking maybe Sunbeams?
