My G -10, as well as all of the others in my band, failed. The micro USB is NOT the way to go!!! If you take the unit apart you can clearly see the problem. The female part of the plug is lightly soldered right onto the 'motherboard" inside the unit. Any bit of slight pressure on the plug will break the solder and the piece falls off. It is next to impossible to repair as all of the soldering points within the unit were NOT done by hand. This is clearly a horrible design, especially for any kind of regular gigging use. The cord should be hard-wired and enforced from the inside. Again, everyone in my band used one of these at one time or another and it failed EVERY TIME!!! Line 6 should make good on this and conduct a recall of every unit.
