IIRC, the Aeros will have a nice tight twist on the pick up wire, Fralins are not twisted from the factory. Also I think if you lift the pick up covers, Aeros have reddish insides, Fralins are black.
Thank you sir. I just installed a new switchcraft jack and noticed the pup wires were multistrand, not twisted.
I will check the underside of the pups tomorrow with a string change.
