My BL had a set of 30 year old D'Addario Xl Reds, Copper coated round wounds sitting around that had never been used. Apparently he bought them way back in the day before decided that he was a better rhythm guitarist than bass player. It seems that they were discontinued quite a while ago. I strung them up on my SB-2, and while they are QUITE a bit brighter than the flats and tapes that I'm used to, I'm kinda digging the sound for a change. I think I'll leave them on this bass for a while. They're forcing me to pay more attention to my muting than I have to with my tapes, so maybe they'll help my technique. Does anybody have any experience with these from way back? Any idea why they were discontinued? Sadly, the only recording device that I have at home is my cell phone, so I won't bother with uploading a sound clip.
