I agree that this is a really poor engineering decision. Micro usb is fine for plugging in a device on your desktop to charge it. But for the rigors of the road and stage? Not even close. Mine just sort of hangs there, easy to wiggle around, and doesn't even insert all the way, maybe 75%. If I move the unit a little bit, it falls out.
All that's standing between me and awkward silence is this little "electronics device" connector, unless I duct tape the hell out of it. I like the unit enough that I may do that, or bring it into an electronics shop and have them hardwire a different type of connector. I'll be trying to get a replacement from Sweetwater. Maybe I got a lemon. I'll post the results.
For stage, give me big, clutchy, reliable connectors, not consumer electronics stuff.
