Studio Equipment list

Since most recording studios list the gear they have I'll do the same-

Computer(s):

2 Intel quad-core MacPro (the second one is a spare) running Pro Tools X with
so many plug-ins that I haven't had time to explore them all.

Interfaces/mic preamps:

Grace designs m108 8 input mic preamp/interface.
Black Lion signature series modified Digidesign Digi 003 interface
Early 90's prototype Grace design stereo mic preamp with Jenson transformers
FMR Audio RNP stereo mic preamp

The above gear (using Mac aggregate mode) offers 16 inputs with some of  the world's best mic preamps.

Microphones:

1973 Neumann U87 large diaphragm condenser
2 Neumann KM 184 small diaphragm condenser
2 AKG C414 B-ULS large diaphragm condenser
AKG P170 small diaphragm condenser
AKG D112 dynamic
Soundelux PTM large diaphragm tube condenser
2 Coles 4038 ribbon
2 Electro Voice ND408 dynamic
vintage Electro Voice EV664 dynamic
Vintage Shure Unidyne SM57 dynamic
Shure SM57 dynamic
Shure SM58 dynamic
Audio Technica AT822 stereo condenser
Audio Technica ATM15a condenser lapel

There's lots of other musical gear, some of which is pictured on this site.
The big room pictured on this site is one of the best sounding recording rooms in the country-live surfaces, no parallel walls, no perpendicular corners.

Let it be said that the most important piece of gear in any recording environment is the ear and instinct of the engineer/producer.
