Hello! Right now, I have a Peavey Mark VIII bass head and an Avatar Neo 2x10 at 4 ohms (cost me $430 total, by the way). I got the Avatar at 4 ohms as I'm planning on only playing for that single 2x10 for like, my whole career. I'm definitely a minimalist. However, I now really that while the Mark VIII sounds fine, I really want to upgrade when it's most conveigent (sp) to a lighter bass head. I was originally digging the GK 700-II RB's, but then I realized, what happens if I need more volume than just a single 2x10? I don't have to worry about that with the Mark VIII as it runs to 2 ohms. I've come to somewhat a brick wall as a lot of heads (good ones, by the way) only run to 4 ohms. So what's the best solution? I would like the head to weigh less than 25 lbs total, as the main reason I want to upgrade is for it to be lightweight, so I can make one trip, head in one hand, cab in other, bass on back. I'm looking to spend no more than about $600 dollars. Or, there's some more options available. 1) keep the Peavey and use that for gigs where you need more power and have a seperate head for just running the single 2x10 by itself that's really lightweight 2) pray to God I'm never gonna need more than 2x10 3) go instead to a power amp and preamp (best alternate option) I don't particularily want to go to the power/pre as I rather have a head, however, if it's truly the best option, I'll do it. So all considered, what do you think is the best option? I'm almost thinking the power/pre, but I don't have a good idea what heads go to 2 ohms. Thanks guys.
