I'm trading my Eden WT-800 for a Mesa 400+. I play in an original band that sounds like Emo meets Killswitch Engage meets Corrosion of Confomity, so I need something with a bit more grind in it. Any tips on these heads? Also I have a question about cabs. Right now I have an Ampeg BSE410HLF and an Ampeg BSE410HSE (one is 4 ohms and the other is 8 ohms) can I still run these with my new Mesa? Or do I need to look into getting a different cab(s)? What do you all recmmend?
