Wah-wah/fuzz pedal, "Jen Double Sound"

Hello Mr.T !
My name is L. I live in Sweden.
I have an old Wah-wah/fuzz pedal, "Jen Double Sound" (Made in Italy). Many years ago a friend helped me to make it to a volumepedal. Now I want to make it to a wah-wah/fuzz again. Is there someone who can mail me a schematic or/and very clerely pictures of the cables inside this Jen model?? I would be so lucky!!!!!!!!!!!!!!!!
Thanks!

Questa è una bella combinazione, ho revisionato il mio Jen Double Sound proprio un paio di settimane fa' ! Ecco un paio di foto all'interno insieme allo schema... Mr.T
