This is a Hiwatt Custom DR103 head that was built by Hiwatt as a prop for Neal Schon of the band Journey, it is unloaded except for the pots, switches and jacks. The "on" light turns on when the switch is on. It was custom made at the Hiwatt factory and has the serial number of Journey stamped on its plate. It is very light as it has no transformers or other electronic components in it. Own a piece of Journeys band gear history!
