Just wondering:  if I’m using full tones and have my disc set to 6 so I can hear low tones on iron, but I also set a notch from 6-35 to knock out foil and small canslaw, I will not hear any tone from 6-35, correct?   I want to be able to hear low tones on iron only.  However, if I set the disc at 35 with no notch at all, I’ll hear low tones on small foil and such all the way to 35.  Is this correct?   Again I’m talking when I’m in full tones.
