Yes, on both counts...and, that's the issue. It does not matter
what the generator produces if the speaker introduces distortion which
may/may not be perceived as a harmonic.<br><br>

<dd>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.<br>

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

</dl>Hello Joe,<br>
<br>
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.<br>
<br>
Thanks for the reply,<br>
