I played on two GK GLX 410s with a GK Backline 600 and I thought it sounded pretty decent for the price bit since the GLX was discontinued I was thinking about going with a GK 410MBX and a GK 115MBX with a GK Backline 600. I don't really know much about Cabs or Heads so I was wondering if you guys thought this would be a good decision. Thanks!
