Porterhouse used ALL ART Dual MP's and a TL Audio Classic for the overheads.
Sky Blue Mind used Mackies on the drums and a Focusrite Red on almost everything else.
Omega had Drawmers, Oram's, Focusrite's, and
the Pro MPA here and there (on the toms as I remember...).
Heavy Brothers used all ART Dual on drums except the overheads which were the TL Audio Classic. ART on Bass, guitars, hammand B3, and voice. The other parts used some the other pre's mentioned.
Just goes to show....
Now, let's talk about the REAL differences in those recordings.
Porterhouse, The Heavy Brothers, and the Sky Blue Mind were all mixed on a Ghost console to DAT tape.
Omega and Waited were mixed on a Yamaha O2R to a Masterlink, but they "enjoyed" the most classA pre's of all the songs.
I just did a test tonite with an acoustic guitar to check out a newer Bellari preamp thingy that looks a hell of a lot like the ART MP single unit. We used a 4033 through Monster Studio Pro 1000 to it, then to a ORAM MWS, a Drawmer 1960, then to the ART Pro MP. Three engineers in the room. We all agreed that the Drawmer offered the best overall tonality, but it sort of lacked depth, but would have been the best pre for like folk music because of the sort of gerthy sound it had. The ART had a much more depth, and with just a hair of cut eq at 177Hz, sounded a whole lot like the Drawmer in the low end, but still had a bit more "sparkle" to the sound. The Oram sounded, well, like you would expect an acoustic in a 80's tune to sound. Not a lot of body, about the same depth as the Drawmer, but a top end that would cut through a dense rock mix well enough IF the acoustic wasn't all that important. The Bellari made the guitar sound like it was a foot farther away from the mic than any of the others.
That was just one mic placement, on one guitar, for one type of performance. I am SURE that any of the pre's could have worked out just fine in any type of production with a little mic placement, and possibly, a different mic to better match the preamp. So while that little experiment meant virtually nothing in the realm of things, it did show me again that the preamps didn't contribute anything to the sound that couldn't be overcome with good engineering work. None of you have to take my word for that, but all three engineers agreed that none of the pre's sounded all that much better than the others on this guitar (a VERY nice Takamine) using that mic.
I am NOT saying don't buy a quality preamp. Rather, I am saying that you cannot possibly rule out preamps that don't cost an arm and a leg as possible good choices. Sweating a preamp purchase is almost silly these days. I would sweat mic purchases MUCH more than a preamp purchase. So many nice pre's available that sound great for half what the class A's cost.
Again, no one preamp is going to define your production. Great production is possible on Mackie's if the engineer learns his mics, his tracking room, his monitors and control room. The most important thing is to KNOW what you are hearing when you hear it, and have an idea of how to use your mics and mic placement to achieve what will work for the song. THAT takes skill and experience. When you get that skill and experience, you will find yourself using whatever pre is available and not really worrying about it.
