I'm putting together a modular rig for clean tones, synth use and in a pinch full PA duty. I'm pretty sure I'm gonna go with one of the QSC models. Looking at the K12 and K122 I see the coverage pattern is different and the enclosures are different materials. however they are both on the high end of weight being over 40 lbs. I am going to chalk that up to build quality. Anyone know if the K12 and/or KW122 are made in USA? I'm also interested in folks experience using one as a bass rig/bass foldback. ps yes I'm still rocking the all tube rig, but decided I needed something that can fill a different kind of role. I also didn't like using my bass amp for my Taurus III.
