Jim, I have also found this imaging problem with my SAT-II on B5 (and ocassionally A5 & A# 5). When I discussed with the good folks at Inventronics a year or so ago they told me that it was due to a combination of factors. I'll do my best to remember them correctly as this was an informal conversation. First, the difference between the partials being read by B5 and C6 and their relative strengths on the piano cause a big difference in imaging. Second, the filters that are used to seperate the particular pitch can change in value over time and cause some lack of sensitivity on certain notes. However, as Ron noted, I too can usually get around the problem by moving the Accu-Tuner around to change the point where I'm picking up the sound. Since this is so easy to do, I haven't bothered with sending my box in for tweaking. My opinion is that it is mostly a lack of sound from the piano rather than an Accu-Tuner problem. Maybe the Accu-Tuner III or Virtual-Tuner or whatever we use next will be able to fix this situation. Good to hear you on Jim.
