Man, I feel for you. I've been touring for years with various Salsa/ Latin Jazz with my upright (5 broken necks to prove it). I usually am at the mercy of what ever backline they provide . In general, IMO, drums+conga = more watts. I don't think you could get away with a clarus. I may be wrong, but you'll certainly need a large or multiple speakers then you have the problem of low end rumble and feedback. You can't bring your speakers on the road so usually you can count on getting a 4x10 cab or a single 15. I found the AI stuff to be on the quiet side to begin with. I'm in a similar situation, having sold all my heavy stuff, and looking for a high watt, great sounding rig that I can take on the road. Preferably with adjustable voltage for different countries. I've narrowed down my choices to
AI Focus around $1200
pros-small,good features for Upright
cons- expensive, actually not that many watts 300 into 8ohms.
Walter Woods-the best but $2500?
Mesa Boogie walkabout- Pros sounds really great....for electric. Probably sounds great for UB. Not as expensive. Pretty loud for 300 watts 4 ohms. A little heavy at 13 lbs, but, compact.
I don't know what the ... to get really but let me know if you come up with any great ideas. I hope this helps a little. Geoff
