Earth G-1000

So I just purchased a G-1000. Killer sounding amp!! It's had some modding done and now has a master volume knob. To achieve this, the reverb pot is the MV pot. This mod has defeated the reverb, and the vibrato does not work along with the bright switch. I found a schematic of the G-2000, but would like one for the G-1000. Does anybody know where I can find one? Also, I would like some general information on the amp. Thanks!
