"Col" by the way stands for Columbia, and there was usually an "RCA" setting also. One preamp that I had, a Heathkit, had separate controls with multiple settings for "rolloff" and "turnover" frequencies (if I remember the terms correctly). These were for the HF attenuation and LF gain so that you could match whatever the recording company had used.
fisher amp question.
