Sorry if I've created a duplicate thread.
Doesn't bother me any. I'm not one of those people that get uptight when somebody posts on a "zombie" thread either. Sometimes later info or questions are just as relevant as hen they were first asked. Sometimes search engines don't get me the posts I'm looking for.
I like the idea of being able to see some lights change to show me that my volume just got bumped up.
Right, so I set up my volumes to be even with amp volume then I can see on rig volume ring: "Ok +3 over that is a good solo volume". And use that as a reference when morphing. Back to noon is my "normal volume" Pretty soon you get to see what is the right amount for volume boosts and can duplicate them where needed. Sometimes clean/distortion sounds will react differently because of compression but that is the reason for the reference so you can start somewhere you know. If you used rig volume for leveling, it would be harder to obtain that reference quickly.
Of course to really set volumes you need to be playing in a mix. I can't tell you how many times I have sat in my room getting clean, distortion and boost levels "perfect" just to find out they are nowhere near close when actually playing live. And the FOH will have a different opinion as well. I will try to satisfy them as a priority, so they're not jacking my levels around if something is poking out. When trying out new performances during soundcheck, I'll ask "how are my clean/dirty/ boost levels? Once I get an OK, I know I'm on the right track and add that to my knowledge setting them up at home. Normally people will set clean sounds too loud and make their distortions sound wimpy when switched. And I found I usually need a LOT more boost that I would have thought I needed at home to get to album "lead level".
