I bought these for my Rickenbacker Tom Petty 660/12.
Great strings. I've been through a few difference sets of strings, yet nothing really seemed to wow me. I could never recreate the sound of when I first got the guitar, but couldn't put my finger on it (pun intended!). My last shot was Rickenbacker strings - why I hadn't thought of this before now I'm not sure, probably down to the fact I've always used D'Addarios. I still do, but not on this 12-string anymore. From now on it'll be Rickys for the Ricky. It now sounds alive, very open and I couldn't be happier.
