Daniel John's & his effects

This is for the die hard Silverchair fans.... out there. Does anybody know what effects Daniel Johns from Silverchair uses? Like I have heard he uses a Boss Hyper Metal Pedal for distortion.... but then.... I heard from somewhere else that he uses a Boss Metal Zone pedal. So I would like a REAL TRUE statement of his gear. Does anybody know what he really uses or does anybody know a site where I could find out?
If anyone can help me out... this would be very much appreciated. Thank you.
