The reverb is out on Channel 2 so I am not sure. At this point channel I & 2 have about the same amount of volume/gain. I am not sure about the tubes yet. I am taking it in to an old tube fanatic who will check out all of these issues. From what I have read online, there are no schematics out there, but he said that he worked on one a couple of years back.
In the picture you can see the cool brown footswitch, It also came with the original brown cloth cover.
