Owned a Shuttle 6.0 12T Combo with the extension cab back in the day and loved it. Should never have sold it. Just got the 350 Combo and wow.! Mr. Genzler did his homework. Blown away by what that little cab does. The lows and volume that come from that diminutive cube is amazing. Adding another BA 210 to maximize the thump to keep up with a loud drummer. I've cycled through other brands of amps lately and while they are all good and have their own particular area(s) of notice, I found myself always looking for something that was missing. Genzler is putting out extremely high quality products! Oh, and the customer service......the man calls to verify orders and returns calls about product questions. Unheard of these days! Very well done!
