Have the GK MB115 and love it. Light and loud. Not perfect but it's a great amp when you consider the price and portability. Using it primarily as a practice amp and the guys say I have more presence than the ampeg 4B pro/4x10 HLF 90 lb rig. At 10 o'clock keeps up with two Vox AC amps and full drums in a practice setting. We're not earsplitting but we do practice at show volumes. Guitar players. Looking at micro amps ampeg b7 and shuttle max. Thought I'd check GK since I'm happy with the sound. Found the powered cabs only to realize if I'd spent a little more money I could have gotten an amp with a direct out to the powered cab. Hmmppfftt. gK tech support says I can get noise out of the XLR out but the line level isn't sufficient to get good results to the powered cab. I'm thinking someone smarter than me has thought about this already. Surely there's a box that I can put between the two that will raise the line level to something useable for the powered cab. Anybody?
