I dunno what recording gear was used on the tracking side of it, but that bass totally sounds like a Spector and I think there's a 12-string bass (or something similar) on Rooster. I remember Cantrell doing interviews & talking about the guitars...IIRC they split each pass out to three or four amps and put each one on it's own track. Like a Marshall, Bogner, Boogie, Rockman etc. and then balance 'em out during the mix.

"Dirt" is a great record...sounds a little bizzare IMHO but it's solid. If you want that sorta bass sound I'd start with a great 'rock' style player...then give 'em a Spector with EMG's, take a DI & semi-dirty amp, compress & season to taste.
