I play in a medium-heavy metal band (pretty hardcore, eh?) and recently decided to go back to flatwounds, having had a set on my other bass some time ago. I decided to try these strings out hoping they would be brighter than the GHS flats I had but still more compressed and mellow than basic rounds. Roundwounds seemed to always have something too much for me; too much bass, too much clank, too much finger-noise. Might have something to do with the humbucking pickups that burst out with a little bit too fat output for finger-playing. These flats are just about what I was looking for: smooth playability with bright tone (not sure how long that'll last though, have read something about Steve changing his sets for each gig ) and perfect for half-step down tuning. They are what I'd call very modern strings (well, they're not exactly modern but have such a feel): articulated sound with smooth, cable-y touch (not everyone's cup o' tea of course). Have yet to try these out at the practice room with distortion and wah, gonna report on that later. I can heartily recommend these to other metal bassists, pickers and pluckers alike (one reason I like flats is that you can pick them without the friction of roundwounds).
