The A-110 manual entry is a little inaccurate:- working back from the 
schematic the tune knob covers a third of a volt in total, or about 
+/- 2 semitones from the central position. The A-111 coarse knob 
covers a volt, i.e. +/- 1/2 an octave, as the manual says; the fine 
knob is one-tenth of this, so covers a little more than +/- a half 
semitone. V. quick measurements on my 110 and 111 seem to agree with 
these rough calcs, so no, you've not got weird performance!
