Just got this from the UPS guy 5 minutes ago!! It's a Mu-tron Octave Divider that has had its labelling worn off. Can't wait to play it. Here's a picture of it with its cousin the Mu-tron III.   |

Don't know why no one's ever cloned this thing |

I'm also curious why there aren't any (at least, to my knowledge) clones of the Mutron Octave Divider. Also, I must confess that I have never heard what one sounds like.  |

It's no more complicated than any other octaver. I prefer the octave down tone of the OC-2, so I'm taking parts of it and combining it with an OC-2. |

A lot of people have said they have the correct schematic for the MuTron Octave Divider. I'll believe it when I actually see a functional clone built from it. And I don't say that to be snarky but because a number of amateurs and professional builders have talked about building a clone and to my knowledge it hasn't happened.
Taylor is the only person I can think of who has created a functional prototype and he said the PCB was the most complicated he's ever done. Considering he's built a Lovetone Ringstinger clone, created and programmed his own bass whammy and obviously conceived and built all the pedals in the Iron Ether line, I'll take his word for it.

Owner, Iron Ether Electronics | | Join Date: Dec 2002 Location: LA US | | FWIW, my build that was really complicated wasn't simply a straight clone, but one that fixes a lot of issues with the original design, while keeping the audio path exactly the same. In some ways, the Mutron is a very crude circuit which uses way more parts to achieve a worse result in tracking than it could. Particularly with regard to fundamental extraction, the method it uses has been greatly superseded. I also redesigned the power supply to generate bipolar 15v from a regular 9v daisy chain.
...not that any of that matters and none of that is rocket science, just throwing it out so that Rick and Spencer aren't raising their eyebrows when Jared mentions it being really complex. It had about twice the parts count of the original, in about 1/8th the PCB size of the original. I don't want to be in a position of defending my statement about its complexity, so it's really not a big deal. I feel a little weird having my cred in question here.
The actual sound generation method is pretty much the same as the OC2: the flip flop output gates a FET, which flips the phase of the clean signal every cycle. The result is filtered to remove the little notches that result from this phase flipping. The only real difference between the two is in the filtering, and making that filter variable will give you all the range of both. |

That was something Taylor had mentioned long ago as a project for his own personal board. He's never said anything about doing a pitchshifter pedal. | | Thread Tools | Search this Thread | | | |
