Isolating the gear is ideal if you want complete control over the mix. If you wanted complete isolation, you would have bass amp in one room (if your micing it, not DIing it... more on that in a minute) guitar in another, with everyone sitting in one room with their instruments and headphones monitoring the whole lot. That way you get minimal bleed from the bass onto guitar mic, and vice versa. And the worst problem is having guitar in the same room as the drums, as you'll get a heck of a lot of bleed onto all the drum mics.
Don't go crazy buying foam and stuff and turning your room into a padded cell! You just wanna make sure that big flat surfaces are covered up with somthing. A couple layers of blanket fabric would stop harsh reflections.
All of the stuff I said above (and in my previous posts) would be a general direction to go in, didn't mean for it to be too specific. To expand on some of the points I've been quoted on
"Dampen as much as possible."
With in reason. Some control and balance works too.
Indeed! Naturally volume matching each other is a very good idea when recording and playing live. That way you can get a natural mix and make less work for yourself afterwards.
"Bass cabs dont really do much for recordings."
They tend to have a lot more character than direct. Might be a bit tougher to deal with too, but...?
Depends on the setup. If its a fantastic cab, then it will add a lot of charachter, as it should do. But chances are if its a mediocre setup, then you'll get just as good results DI as you would micing it, without all the hassle.
"Rule of thumb is : when recording, have no room ambience at all."
Some of what you get with a bit of spillage you can't get in a box.
True.. but the room ambience of my sitting room isnt going to be as nice as the resonance of a recording studio ... All to a certain extent
I have yet to experiment with fiberglass... could be interesting! heh
