Nah, modern hi-gain like Mesa, Diezel, Engl et all have a ton of gain baked in and available. Tubescreamers and Boss SD-1 pedals were used with the gain very low, or at zero and the volume up to push the front end on Marshalls and crunchy 'British' amps to get the valves cooking. It's just a clean boost to saturate the valves and kind of acts as a preset EQ.
Edit to say, with a Marshall or Laney type amp it still won't provide that Peavey 5150 chainsaw type distortion. It is a 'cleaner' drive. Even with heavy metal, this is still very popular for recording, maybe not so for live use.
