Yeah, I love the ohm selector on it and it is pretty f'n loud. I haven't fully dimed it yet, though. Kind of scared to in case I fry my speaker. It's a Carvin 18" 4 ohm 500 watter (1000 watt program,) but I'd like to eventually replace it with an 8 ohm Celestion so I could also have the option to get another cab down the road to stack, if I want to. I thought the Speakon only was annoying at first, only for the reason that those cables are so damned expensive, but it does work rather nicely so I suppose it's worth it. I got the head extremely dirt cheap, anyway.
