True barn fresh, this one will need some service before use. I did test it and it did work. The reverb did work (tank has a lock on it for transport) I played for a few min, and did pass clear audio.In fear of the Astron caps that are in it, that look like they need to be changed I did not "crank it up" in fear of damage. DEEP reverb, however I noticed that the footswitch didn't work, however is present with the amp. It appears that someone at some point put an audio jack on the back, which could be easily disconnected.
As you can tell it needs to be cleaned, checked out, and is truly estate barn fresh AGAIN it DOES HAVE THE BACK PANEL it was taken off for the photos. THIS AMP SHOULD BE CHECKED OUT BY A QUALIFIED TECH before use and caps/resistors changed as needed.
