does anyone know what Mic Pre is used on Linkinpark Hybrid Theory VOCAL RECORDING for Chester Bennington(THe singer)?

A lot of people seem to love the analog vs digital battle but I wonder how many people record with a hybrid set-up like I have. Since I started with a 1/2" 8 track room in 1989 and then went digital in 1993 I decided to keep as much of the old gear in service when appropriate. For example, I like to track drums and guitars to tape.
