Tuning with a fork [fork partials]

Hi David,

I realize that.

However, I don't think the distortion could be considered an harmonic, which is what the question asked.

  John:

  I'm sure that the Accufork and TuneLab both produce a sine wave.  Howver, unless you have a very capable speaker there is going to be distortion there and partials added.  It takes quite a good speaker to reproduce a 440Hz sine wave with no distortion.

  Hi,
  Al Sanderson told me that the Accu-Fork, gave a pure tone, with no harmonics.

      To check your accu fork open the battery compartment and look for a little

    Hello Joe,

    Thanks for the info. I didn't make myself clear. My AccuFork is right on pitch. What I was wondering about was if the harmonic content of a newer unit was any different from the partial-rich output of mine.

    Thanks for the reply,
    Bob Davis
