I don't know, guys. I don't buy all this shit about tube warmth playing a big role in modern recordings. Tool is a great example. Their sound is STERILE sounding if I have ever heard it. Overprocessed, and industrial sounding. You need a mic'ed tube amp, nicely recorded for what? Only to overprocess it, digitize it and make it sounds sterile?
The same goes for just about any DAW recorded heavy guitar. Once you have it in your PC, it is all 1s and 0s. How can you have "tube warmth" well represented in 1s and 0s? Just about every rackmounted effect nowadays has digital converters in it, and so do a lot of stomp boxes. Is it really THAT far of a stretch to think that you can model an amp, skip those steps and still be not get a good sound? I just don't buy it. Tube amps are circuits, circuits are logic based, and bound by the principles of physics. Now while you can't quantify what a guitar player does, you CAN measure what a circuit does to a signal. It isn't *magic*. Every component effects the signal, and every component will predictably act a certain way in the circuit, within tolerances. Even tolerances can be accounted for. Someday, and it won't be long, amp modelers will be as commonly accepted as DAW's. In fact, the same arguments were made by the hardcore analog people clinging dearly onto their reel to reels. "You'll never get a decent digital recording..", "digital recording will never sound as good as analog.." well maybe not, but it only needs to sound as good as the record buying publics CD Player's digital converters....because anything more won't be heard anyway.
Just food for thought.
