There's a 300 watt Sunn PA head on Craigslist for $150, $400 for that and a pair of Peavey SP-2's with Black Widow speakers... My bass sound is with a lot of pedals anyways, so I often don't rely on the clean tone of the amp... Would this be louder than my Hartke HA2500 (which would be 250 watts with 2 4x10 cabinets)? Would it sound like dogpoopie? Could I plug my cabinets into said PA head? Sorry for the questions, I just never thought of PA heads as a way to get more volume until now!
