'Scooped' can also be described as 'smiley face EQ'. On amps like my old Trace Elliot, it had a 12 band EQ (12 individual sliders) on the front of the amp to set EQ. For a 'scooped' tone, the sliders were set so that they resembled a smile ( ) for a tone much favoured by slappers.
Slappers..... at a recent gig there were these 2........No, I won't go there.
