Everyone talks about how good their Halfrounds sound on their fretless basses but what about on fretted basses? Im looking for strings for a new bass that is being built for me. It is basically a P-bass copy. I know tons of people prefer Flatwounds on their P-basses for the thump factor but how do the Halfwounds sound? I play in a melodic southern rock/alt. country band and was wondering what I should be putting on my new P-bass. I usually use roundwounds on my J-bass and this will be my first P-bass. Im worried that Flatwounds wont have the sustain I want so Im looking at Halfrounds now.
