Adjustment value issue in tuning mode

On a new LP Tribute purchase, the fine tuning don’t seem to work properly : more precisely, when I turn the fine tune knob all the way to the left, the pitch is still higher than normal (about quarter of a tone too high)
The OS is 1.03 and in the tuning mode, the set of extreme values I have is : -1024 to +1023, instead of -2048 to +2047 as stated in the manual (p.6 of the update edition).
Have someone an idea of what’s going on?
(note : I haven’t tried any autocalibration yet)

Thanks you for your help

My Little Phatty T.E. was out of tune till I ran the autocalibration its in tune now try it.

By all means, try a complete calibration. Afterwards, “concert pitch” should be found at the center of the Fine Tune pot’s range.

As for the range of the fine tune, the manual is in error. -1024 to +1023 is the correct range. This corresponds to a Fine Tune voltage of -2.5V to +2.5V, where the other controls have a range of -5V to +5V. I will make sure this is corrected in the manual.

“Khoral” asked me to thank you for the answers, and to tell you that the autocalibration solved his issue!

All’s well that ends well! :slight_smile:
