Lynch used some overdrive stombox (OD-1, TS-9 and such) and ran an amp at moderate gain level into clipping.
If that is what JB is doing i will apologise but it certainly does not sound that way in the clips, it sounds like he uses way too much destortion scooped or not is not the point really.
Sorry to put it so bluntly, not my intention really, i do however tend to be clear on what i say.
