It was from a Sony transistor Radio from the 60's my mother had, which had bass and treble tone controls.. I was always trying to equalize the sound of the music the radio was producing.. The bass was always thin, so I boosted it to around the 2:00 position, then set the treble around the 12:30 position or slightly higher... then, would adjust the volume to where she liked it.. My Mom always like the way I set those controls... but hated it when I got too obsessed with playing around with her radio!
