This is the one feature that I really wish the K2 had. My TS-940 and
756-ProIII both have this, and I find it very helpful. It's not only
nice to be able to customize the sidetone pitch, but I like to tweak it
easily via a front-panel knob every so often during long operating
periods, like contests - adjusting the sidetone (and zero-beat point) up
or down a little from time to time seems to help minimize ear (or is it
brain?) fatigue.
