Yep and it likely wont yield much in quitting down your amps for the effort. If you have the room and can build staggered studs, you can throw on 2 layers of 5/8" drywall that would be separated from the exterior walls and reduce sound transmission. For the ceilings you could either do those isolation clips or drop the ceiling on the new frame and then do another layer or 2 of 5/8". A good solid core door with some weather stripping and you'll have a pretty solid room. A few corner bass traps and some other light treatment and you should be able to push some volume in there without shaking the walls in the rest of the house.
When I built my studio/rehearsal room I did 2 layers of 5/8" on resilient channel (decouples from the framing) and all the walls were sitting on neoprene rubber for decoupling as well. Some other things that helped:
-Meticulously sealing every gap.(door gaps, electrical and light boxes)
-A heavy as fuck removable window plug
-No HVAC vent in that room
-Gear closet between the control room and the live room (air lock)
After boarding 2 layers of 5/8" on the ceiling, I was pretty much done with drywall
Both layers had to be mudded, but only the top layer had to look good.
