Rocker Jack White is so used to playing the guitar at deafening noise levels, he can no longer tell how loud it is.
The White Stripes and Raconteurs star always cranks his amp up to the max - but only realises the exact volume when sound engineers show him decibel readings on a meter.
He tells Rolling Stone magazine, "I need to feel it (volume). I've gone through things where I go onstage and the sound guy at soundcheck comes over and he'll hold the decibel meter and show it to me while we're playing - and it's 127 decibels.
"That’s not good. And I can't even tell. If it's not right there, it feels wimpy, it feels uninspiring."
