I just got a new Hartke HA3000. I was excited to find it because I don't think Hartke makes this model anymore. I'm looking for advice from users of this amp as far as how you set the EQ and "special shape circuit". Make sure you include what style of music you play. And it would probably be good to know what kind of cabs you are using. I'm playing through a Hartke 210XL at the moment (and am looking for a 15). Thanks!
