Doh, I can't say "Everything" even though I'd liker to
I'm using roundwounds on one bass, bought Supernils on a whim, but I prefer Evah Pirazzi flats on all my other basses (kept breaking the Obligatos)...
I use EP solo set, "bumped" ie I tune them to regular pitch.
I prefer D'Addario XLs for their tone but since I mostly play custom sets made up of singles it gets kinda pricey with those. Ernie Balls singles are much more reasonably priced so that's what I've been playing mostly.
