I really like my Catalyst but I get the feeling from watching the Line6 videos that clean and edge of breakup tones were the main focus of the amps designers.
I wish Line6 would throw in a few more variations for metal / rock.
E.g. a proper JCM800 (instead of the more vintage sounding Voltage (Crunch)), and a Metal amp (5150 or similar) variant to add alongside the Oblivion (the only Hi Gain model in the amp).
Come on surely it time for an update. The amp has been out a while now.
