I play bass in a post-hardcore/sludge band, and we usually tune down to C, i play a 4-stringed bass, and i have trouble with pretty much fret buzz when the bass is tuned down. Right now i use Ernie ball Power slinky (55-75-90-110 set) roundwound strings. They sound good and that, but the problem for me is the fret buzz. Now i'm thinking.. wouldn't it be better for me trying like the Rotosound RS665LB (5 stringed set 35-55-70-90-120) and just remove the lowest string, and then tune up a half step? i mean, it cant do much negative to the bass tuning up that little. and that would certainly remove the buzz, as it will get alot of higher tension.. i could probably even lower the action a bit. what do you guys think?
