Does anybody know where I can either download or locate information on patches for a Boss GT-3 pedal board. I have had this board some time and have only just found out that you can program from a PC and that there are patches available on the net that you can either upload or manually enter.

I am specifically looking for some patches that give a 'Metallica' sound!!

Many thanks in advance
