Hilarious, isn't it? When everything is set at noon, you can't even flatten out the mids, let alone boost them; at the same time, the range of the sweep is rather wide and mostly focused on cutting the mids. To be more precise, the frequency band is around 500Hz. From 12 o'clock to the max, the knob provides a 4dB boost; from 12 o'clock to the min, it cuts 12dB (in a narrow band, which is once again part of the "magic"). At the same time, the overall gain across all frequencies has a 3–4dB range (in other words, the MIDDLE knob adds some gain). That's the secret to very mild and organic control over the mids. Wait, what about the BASS and TREBLE knobs — don't they have an impact? You bet they do! Let's look at the BASS knob know.
