i understand
no stones just want you getting as Johnny said “ what you paid for”
now about the spl meter... my understanding is that Vandertones are compensated to adjust for non linearity of the R Shack meter
i have used Audiotools and a calibrated microphone with the Vandertones disc with ok results.
note also the analog eq centers are not what you typically see on an RTA as they represent typical room issues versus octave intervals....
so for best results buy a meter meter and download vandertones
