I've been using EB Bass strings since 1980, nothing else, I recently changed my precision's strings to cobalt and wow amazing... i ended up buying a whole box of EB Slinky Cobalt Bass Strings 100's, now all 5 of my basses have them on. Incredible sound, smooth silky touch, and soft tuning man. I also changed my Guitar strings to EB Slinky Cobalt 9-42's and wow again, amazing sound, touch and feel. Way to go EB, you only get better with age!!!
