I saw this on Music123.com It says its a Hartke 3500 mounted in the hartke VX410 cab. Does any one own this or has tried it? i am very very curious, I like the 3500 very much, I would like it even better in a combo. Qusetions: Does it put out 350 watts, or 240 watts? Can i add an extension cab if 240 watts? How does it sound?
