Ok, heres the scenario: I was going to pick up a used EA CXL 112 with an iamp 350 for about 750 USD. However, the iamp has been sold, and he is now getting in a markbass S450. The cost is going to be about $100 extra, and it has an extra 100 watts. He told me that if i eventually want to grab a second cab and get loud with a band, the iamp 350 wouldnt cut it, and that the markbass 450 would. I like to play hard rock and a bit of metal, so think mainly sabbath, hendrix, but also a bit of maiden, metallica, etc. If i do pick up another cab down the road, it would be whatever size i would need it to be to get loud enough. I play a G&L L-2000, and ive heard that both markbass and EA are good at transparency, which is good because i like the sound of my bass. Anyways, the question at hand is: How powerful is the iamp350? Strong enough to be heard in a loud band? What about the markbass S450? Strong enough to be heard in a loud band? Worth the extra price? I'm not looking to cut through, but i dont want to be non-existent either, simply to be heard. And dont tell me to not get the 112, i love it and my mind is already made up on it. This pertains purely to heads. Thanks!
