Auderes are not an official option right now. Only Bart and Aggie. It's not a big thing to retro fit one although, I firmly believe the two stock pres sound way better.
The only pre that I would even consider in my Roscoes other than their stock Aggies is an ACG Filter. I have a double MM bass that might sound even more Wal-ish than it already does with that one.
