Specifically to standard configuration Teles, it depends on what you have and the era of pickups they're aiming at. Mine are aimed at the 50s style and they're pretty hot, so with a decent gate you can easily get some pretty brutal tones. Some of the later 60s/CBS types can be a bit lower output and hard to get much push, as well as having a lot more treble response. Noiseless and other variations are different again; the American Deluxe I had with the original noiseless could do high gain pretty well with a solid boost, I just never really gelled with the guitar and I don't like the 6-saddle bridges on Teles.
