Yikes. Saw 'em after Technique came out; Mr. Hook was playing his custom hollow-body 4-string (at about ankle height!) through a huge rack full of stuff, damned if I could tell you what was in it!
But the ears indicated a touch of chorus, maybe a smidgick of delay? Even a bit of reverb, perhaps only on the high end, since the low end was, as always, super-colossal. The overall sound was one of humongous punch, with "air" and clarity, and a bit of sweetness on top. Does that help?
