what we've got here is a collaboration special: r_U_sirius profiled his Laney Amp. I played "Iron Man" and fellow user lightbox tweaked the rig!
with courtesy of Sirius we are proud to announce the definitive sound-like-Iommi-in-the-70ies-rig! enjoy!
the story of this collab is in this thread. The rig has been uploaded five minutes ago.
