I played two p-style basses that I really liked the sound of the other day in GC and I am considering switching out my current strings for what I was noodling on. For some reason, I keep missing the tech guy and the other employees are not really bass players and have been unhelpful in helping me identify the brand I was playing. They were also unwillinging to crack any packages open to compare. Can you guys help me identify what I was playing before I buy for myself? I think that I was playing D'Addario Chromes in both cases, but I am not entirely sure. I know for sure they were both flats. Both were a dark grey in color. Both had fabric winding on the tuning machine end. The first were blue, the second green. Just based on feel (I have no prior experience with flats) my guess is that they were both Chromes sets, and the blues were regular gauge, the greens a heavier gauge? Am I on the right track? Thanks for your help!
