Acoustically-recorded records did NOT use a standard "curve!" Their 
equalization was entirely
dependent on the acoustic characteristics of the recording horn...as well as 
the mechanism
used to play them...!

Even earlier electric recordings did NOT use a specific curve...tone 
controls were
individually adjusted for each recording, and actual characteristics were 
dependent
on control settings which are no longer of any use to-day...!
