Reverbs are not associated with rock tone, which came from the Marshall Plexi, JMP, JCM models, all non-reverb.
Many many amps are based on those Marshalls and their tone, so that is why Soldanos, Cornfords, Friedmans, etc, usually come without reverb.
If reverb is needed, people also use rack/pedal effects and the digital kind to get more variety.
