there really isnt much on here about these strings. But i put some on my bass yesterday the 45-105. They are AWESOME! they feel good they sound good. the only thing that kind of freaked me out was the E and A are tapered at the bridge. never seen that before . but that is the way there are made. something to do with different sound. I even played a p bass with the Nikki Sixx helix strings on it. sounded great!!!! so now im putting some on my p bass. anyone else tried them?
