I know tracking on octave pedal depends on many factors, but I thought it's weird because it tracks all the way trough sustain on 15th fret on A string(Note C) but the tracking would be glitchy and on and off on 10th fret on D string (which is same C). I can definitely hear pitch shifting after half second into sustain on 8th fret on D string. and crazy part is below 12th fret, some random notes are having tracking problem, but some fret right next to it works great.. like 8th fret on D string won't work but 7th fret works but 6th fret won't again. very strange.. I checked intonation of my tune and they are pretty accurate. thoughts? oh and sometimes my pedal is turned on eventhough the LED is not lit.. what the hell? this happens when I plug in the cable to the pedal. or after plugging in the power jack. I did not turn on the pedal but the effect is active.. I would have to turn on the pedal again and hit the bypass again to kill it..
