i have a gretsch g5123b. i've been told to get flat rounds for this bass, but i don't like flat rounds, unless when it's appropriate to use like for jazz. i've bought D'Addario long scale half rounds 45 -100. right now i'm using D'Addario long scale half round 50 - 105, which sound good, really good when new. next i'm thinking of getting the same but higher gauge, 55 - 110. i play rock, btw. i got the half rounds because i wanted the flat slide with a round wound sound, best of both worlds. but from watching this video, leads me to believe i could find a flat wound with a round sound. i don't know if i want the low end growl. what strings should i try my bass next?
