Hi. I have a couple of questions about building a Mesa rig. I'm kind of gear stupid so if I sound out to lunch I apologize now. All I currently own is a Godin 4 stringer with a passive P style neck pickup and a J style bridge pickup. I sold off the rest of my bass gear back in 2005. I'm looking at either the Big Block 750 or the C9. I can't easily try them out first so I need to learn as much as I can up front. I'm fairly certain that I'm after a fatter rock tone. Alice in Chains, Melvin's, Metallica... Stuff like that. I need something that will sit well with a Dual Recto in the mix. Also, I need some suggestions on what cabs to match with it. I'd like something semi portable...enough to use as a monitor, but I also need to be able to scale up as many of the venues around town are small rooms that have minimal PA systems that don't carry much more than vocals. I've used 8 and 15 inch speakers in the past but have no experience with the 12 inch speakers Mesa has and am wondering how a pair of their 1x12s will perform?
