Les Paul Signature Low Impedance Pickups ?

[indianation65]

Does anyone else own either a Gibson or Epiphone Les Paul Signature, double-cutaway semi-hollow with the two f-holes? I have two of them, and my question is regarding the Electar low impedance pickups. There is next to no material on the Electar Company. The pickup/tone selector reads 50/250/500 ohms for a basic single coil, p90 or humbucker tone. I can’t find anything on the pickups output. I’ve learned that 500 ohms does not equate to 5.0 k output, and so on. Does anyone know what the basic output is supposed to be? I know hooking them up will tell me, and I will at some point, but not now. I was just wondering…thanks!
By the way, they are fantastic axes. My laptop is on the blink so posting pictures is a chore, but I'll try.
