When I bought a used bass a couple of weeks ago, it had non-factory strings on it (of course). They need to be replaced, but I'm actually pretty happy with the construction and sound and I'm contemplating replacing them with new strings of the same brand. The store had no idea, so I'm hoping perhaps someone here could take a swag at it.
My guess is that the red wraps indicate GHS boomers, which I've used before and am OK with. But I'm sure there are other strings with the same construction, so...
Here are two threads with pics. Hopefully you can see the strings well enough:
New (to me!) Ibanez 5-string - model? B string intonation/action
