I'm trying to put together a new rig for my blues gig, and I *think* I have it narrowed down to the Fender Rumble 200 or Carvin MB15. The Rumble is getting rave reviews, and I was almost ready to pull the trigger, but then I stumbled across a thread about the Carvin MB-series amps - also getting great reviews. The Carvin MB15 is a little less expensive ($30 less) (and has a matching 15" cab available, for some 2x15 joy!), and also has a bit more power, and custom colored Tolex covering options. It is also a wee bit lighter. I also like the direct-out having a level control, which the Rumble doesn't. Feature-wise, the Carvin beats the Rumble hands-down. But, I can not try one before I buy. That has me a bit worried. The Rumble200 has been getting such great reviews, and I can actually try one out at my neighborhood GC. That definitely adds to the "feel good" and comfort factor. So, my TB gurus... what are your opinions? Other suggestions?
