OK Really getting tired of so called plug n play crap. just bought the amplify 150 and it will not update the firmware. I downloaded and ran the Line 6 updater... my PC recognizes its there. But I put it in update mode turning it off and on holding down tone and tap bla bla bla.... and the POS still won't re-flash. Im ready to ship it back. Anyone got a fix? Thanks very much. Line 6 is no help what so ever. without the tech functioning properly this is just an expensive solid state amp worthless as far as I can see.
