The only reason that I'm deducting one star from my review is because, due to work pressures, I've only had one opportunity to set up the rig and play some guitars through it since it was purchased. It is a substantial product and quite heavy. The plastics are high quality and durable so I would expect it to have a long life, particularly if being used for gigging purposes. The feature set is also impressive given the price point and I look forward to many hours using this PA system when time allows.
