Quotes from Jason Suecof and his asst. engineer Mark Lewis:
Slim [guitar] tuned down to A, so Mark upped
his string gauge to .70! It sounded brutal but
still needed the 6505. Once again the tone was
crystal clear. Bury Your Dead does open three-
chord stuff, and I think the 6505 works especially
well on anything with that machine gun-style
riffing. I dont think theres anything that breaks
through the crunch better. I think its the heaviest
tone weve ever gotten as far as bands that have
a more chuggy/dancy/punch sort of feel to them.
Were doing their next album, and you can bet
were gonna use that again.
The sounds of that record have brought us a lot
of clients. I wanted a bit more saturation, and the
6505 has that thicker, more saturated midrange
that fills out the holes [other amps] leave. Another
thing that makes us very fond of that amp is the
way that it takes EQ in mixing. Weve had some
amps sound absolutely crushing in the live room,
and then we mic them and they flat-out dont cut
it. Some amps dont take to being EQd well and
start to sound plastic and processed. The 6505
really allows us to shape what we hear in our
heads.

They were referring to "Beauty and the Breakdown", if "Cover Your Tracks" is the next album Jason spoke of, there you go. I'm sorry that I am not familiar with Bury Your Dead but I remember reading this interview a couple days ago and thought it might help.
