Got my new MAG300H head on Saturday. MAG owners - thoughts? 1.) Fan is pretty loud. I haven't had a head w/ a fan before- is the MAG louder than others? 2.) Sub harmonizer seems pretty useless, but I haven't tried it out in a full power situation yet. Ya really got to crank the bass frequency for it to be audible... 3.) The head is set so far back in its case, that when it sits on my 410T cab, I pretty much gotta get on my knees to see the controls and adjust them - shoulda got the rackmount version I guess. 4.) Good power and nice sound - but it doesn't blow away my old acoustic 470 solid state head. Thought 30 years of technology would be an unfair advantage. Nope. Go acoustic control corp! 5.) My passive jazz bass barely makes the needle move on that cool VU meter. If I crank up the input control I get lots of break-up. all said, a good amp for the $$$. Debating whether or not I need the MAG 210T to round out this rig. Thinking so, to get the full watt potential.
