Re: addendum OK, it's the Small Tweed #2 based on a 1960 Champ. This should be SE. A tube direct box is not necessarilly SE. You can build a tube direct box with ballanced circuitry (differential pairs) and this would clip symmetrically. I guess that another model in which the assimetry should be fairly obvious is the Soldano X88 (Modern High Gain from the front panel). It's a preamplifier (no power section) and it's designed to emphasize the even harmonics. |

Ah, and the Fuzz Face should be very assimetric. |

SteveF | The waveforms on the Soldano and Fuzz Face are both so crazy it's hard to tell for sure, but they each appear to be symmetrical to my eye. |

Guys, I will be picking up a POD next week. I will do some quantitative analysis and write up something with waveform and spectrum plots. But I don't have a web site... Would anyone like to post it? I guess I could look into the free web sites. Thank you, John Kos |

POD asymmetry Here's an idea for someone with a POD to try: If you have a TS type circuit such as my Son of Screamer, you can remove one of the diode clippers so that the signal is only half-wave clipped. This will introduce lots of even harmonics. I might even suggest only using 1 Ge diode as a clipper in the feedback loop of the first opamp. Drive the POD with this signal (tone control neutral), and see if it improves the amp-like sound of the POD. regards, Jack |
