Joe B fuzz face help.

hey all,
I just got a used Joe B fuzz face! I am super stoked but the guy i got it off said he messed with the internal trim pots. The pedal sounds cool, but i really want to have the pedal set to the right specs. I contacted Dunlop and they said i had to mail them the pedal to put it back to spec. The down side is it will cost me $50 and will take a month. SO if anyone can help me save $50 and let me know what voltage there Q1 and Q2 are this will help me get the pedal hopefully back to the right place. Or even a photo of the trim pots to see where they are set?
Many thanks.
