I agree with everything you said
also live sound and studio sound are 2 seperate beasts as well.
Like I said I don't use amps to record with other than Preamp and DI or a
1/4" phone Jack to a lowZ transformer.
I use a Mesa amps on stage and the finished tracks I posted are dam near identical to our live sound.
It works for me
some other setup may wok better for someone else
There is no one single configuration set in stone to determine how someone should or should not lay tracks.
If someone commissions me to do some recording for them and they want to use their amps to put into the chain, hell that just makes less time I have to spend mastering their tracks.
