I’ve used Rotosound 77’s for years and years on all my Basses- fretted and Fretless. Just picked up a brand new P bass, took off the rounds that came installed and though maybe I’d try something different- D’Addario Chrome flats. Thinking that was a bad move. Been on about a week, and they seem to be combine the worst of flats and rounds in one expensive package. they sound zingy like a round (which I don’t like). I know it’s a new string , but it is so metallic I have to boost the bass and dramatically cuts the mid-highs on my amp to keep the bright metallic zing from taking over everything. They sound far more metallic than the nickel rounds they came with. They’re sticky, almost like they’ve been rubbed with... I don’t know? Wax? Lubricant? It’s quite fatiguing to play them since it almost feels like I’m fighting the coating. I’m not a bass shredder or anything, but it’s like working out with ankle weights. I’m in Australia and it’s not cheap to replace your bass strings- this set cost me nearly a hundred bucks, so I’m stuck with them for awhile should probably just stick with what I know works next time!
