    Does anyone know where I can get an "octivider?" it has a pick-up which attatches to the mouthpiece and sub divides the fundamental into 1/2 and 1/4 frquency to simulate trombone and tuba.

    A pickup on a mouthpiece? Can you explain how this works - with a picture would be nice.

    In the 70's I used a transducer on my trumpet and had it connected top an "Octive Box", also used a phase shifter and a wah-wah box.

    I don't have a picture of mine, but here is a trombone mouthpiece with a transducer on it used the same way.

    Barcus Berry used to make transducers for brass instruments, using a piezo microphone. The original Octivider was, I believe, analog--but now many digital harmonizers can do the same. Some other neat toys: NoiseFX - Colorsound Octivider

    Yep, had a similar toy in the 70's, a Condor RSM made by Hammond Innovex. Analog, noisy, cheesy, but really kinda cool.

    In the '70, in a summer concert in southern France, I heard Dusko Gojkovic playing with that thing : the trumpet was simultaneously doubled an octave lower, like a trombone. Amazing !

    Wow, I haven't heard about these things in years. I remember trying something similar in the 70's that plugged into the water key port on the tuning slide (or you could add a fitting to the tubing with a cap to close it when not in use. It seems like you could multiply as well as divide the octaves - lots of guys could hit double C! If I remember correctly, Don Ellis used one on occasion. It would be great fun to find something like that again!

    The RSM would do 1 or 2 octaves lower, and 1 octave higher, but it wasn't a natural sound. It could also generate different sounds (clarinet, organ, strings, etc) that sounded like a cheap home organ.
    We also had a GSM for guitar, which used a hexaphonic pickup which we used almost exclusively as a bass substitute (we were a trio) at times.
