My wife got me a Boss OC-2 octave pedal for Christmas and I really like playing with it. But I noticed that it has a tendency to cut in and out of playing the additional octave whenever I play a note that's longer than a quarter note. It sounds almost like there's a short or a wiring problem in the pedal -- I'll strike the note and you'll hear the root+octave but then it switches erratically in and out of the octave. I have noticed this too on an amp that had a built-in octave effect. Is this normal? Is there any way to get a more consistent sound from the pedal on longer notes? BTW, The pedal itself is brand new and the battery is new. And I am playing only with the first octave below the note -- the second octave is turned all the way off.
