with one of the Micro 2-10 cabs. Is this a significant improvement? 100w combo rear ported 12" to 200w & 2 sealed 10"s? The SWR almost cuts the mustard, esp w/an extension cab, but not quite. Like the idea of this but afraid it won't be a big enough improvement to justify the investment. Dont play in a stupid loud band but I need a bit more. I play Upright 60% and NS Guild Starfire or Pbass 40%.
