I'm in shock... My current rig is anAmpeg b4r headinto an eden 410xlt, ampeg 410hlf and a sonic 18 cabinet. I wanted just little more power forthe 410xlt. I just picked up a barely used carvin r1000 head I got the carvin to run the eden,and was planning to use the ampeg to run the the other 410 and 18. I've seen all the back and forth on this board discussing if carvin's amp's are god or bad. Well in my opinion, they're incredible! This head going thru my xlt blows aways my ampeg doing the same.. I'm honsetly and pleasantly supprised. Not that my opinion matters to anyone here, but I thought I would let everyone know anyways..
