Cutlass RS vs HT Models?

I believe the RS simply refers to the roasted neck, which I love. But how do the pickups compare? Are there any other differences in the models?

I prefer an ‘old school’ sound in pickups, and in my mind I get the impression that ‘HT’ pickups have a more ‘hi-fi’ sound. I’ve seen some older RS models for sale, which got me wondering.

Any thoughts from someone who has owned both?
