i was actually considoring something like that, but for now im looking at what i need most portability. my 400 pound rig isnt exactly easy to transport (say if i wanted to do a small gig it isnt exactly ideal either).
I'm interested in a 2x12 at the moment for smaller gigs. I would love to see what you're putting together once you get up and running. Where in MI are you again?
Depends what market you aim for, your average metal guitarist will want a 4x12 because bigger is better in the metal wordl (even though it isn't) but to the sort of people that lurk around internet forums then I think you would be good.
