This is a wierd question, but is there any way to tell these strings apart? I just bought a used Fender JP-90 (very cool bass BTW) and the dealer I bought it from replaced the nut and put new strings on it before he shipped it. I called him and he said he either put GHS Progressives or Danelectro strings on it, he couldn't remember which. He thought Danelectro. I'm thinking maybe they're Progressives, because of their bright, clean, semi-aggressive sound. They have a rough feel and look more-or-less like average nickel roundwounds. No silk. I'd really like to know what they are, so I can get the same thing next time. I haven't tried either of the mentioned strings before.
