Went through a phase where I put these on every bass I saw. Now I'm enjoying nickel rounds again so I will part with these. One set brand new in box unopened: $50 shipped CONUS One set used on Fender Jazz STRUNG THROUGH THE BODY. I emphasize this because they have a little hump where they went over the saddle and if you string through the bridge it will be further down. I bought a used set previously that came this way and used them on a bass that strung through the bridge and it did fine, but I just want it known. I really don't know how old they are but I would guess less than a year. I bought 2 or 3 used sets here and I'm not sure which set these were. How about $25 shipped CONUS. Both for $65 shipped CONUS. That is all.
