What do YOU think of when you think, Reggae?
I think feeling it. I think protest and passion. I think big bass, and the classic Bob Marley, Dennis Brown, Jimmy Cliff, Sly & Robbie stuff, to UB40, Steel Pulse, Burning Spear, and assorted Ska & RockSteady things.
Actually, I like almost all of it because the bass and drums are the rhythmic engine room, the voices are supreme, and the chordal instruments just keep time instead of driving all the time!
Haha, I've been so sold on trading my Ampeg setup for a lightweight, loud, clean MarkBass setup, hoping people would either encourage me or suggest something different.
It looks like I could sell my SVT-CL for $1,000 or more, from what I see on eBay, etc.
See my previous post about selling it.
What would YOU suggest I buy in the lightweight, thick, warm, loud department? Little Mark 800 Tube?
IMHO, a 2 ohm capable head with at minimum 600 watts into 4 ohms, and a pair of top notch cabs with good low end and clean mids is what you need. Since you want light, as most of us do, that means one of the newer hybrid heads, but most of those do not do 2 ohms. You should be able to get a great light cab used weighing under 65 lbs for ~$550 or less. I'd start with 4 ohm 410, but that is just me.
There are light power amps that do 2 ohms, the Mesa M6 and M9 do 2, there are certainly others.
Cabs? I suggest you check out fEARFULs, Avatar, GB. Bergantino, Mesa, Aguilar, (there are many others), etc. In other words, you have got to do some home work to find what you like.
I really dig my Epifani UL1 4 ohm 410 and UL1 8 ohm 210, but not only are they disco'd, that company has changed a lot from what I have been told—not sure what so say about that.
Since you are in So. Cal, there must be tons of used gear washing up on shore, LOL!
I'm kind of going out of my mind, wanting to change rigs, but afraid that the outcome might be disappointing...
Few things are certain. A new rig is a gamble, but it is not a marriage.

BTW, BurningSkies is THE guy to ask about fEARFUL reggae rigs, and check out his racked pre/power amp setup. Nice and light. The one I have is ~74 lbs. I am waiting for my M9 to come home from Petaluma. Gotta go to my gig. Later!
