Octaver Schematics

Discussion in 'Effects [BG]' started by Diogo Melo, Nov 4, 2002.


  1. I'm going to build my self an octave. Just wondering if any of you have the schematics for a EH Octave multiplexer or some other good octave I could build. Thanks!

    oh??? Do tell!!! Hey bigfeet, I can pick up a bbe sonic maximizer for 250 canadian (used) is that a good deal?..

  5. I'm thinking of moding my EH BMS so I have a decay control for the amp section, I've just had trouble finding the schems. I may add a wave shape for the square wave generator too...
    Uh, you sort of hijacked this thread but I'll answer your question anyway... That's not really a good deal, you can buy one here new for $150 now, that's about 230 CAD.

    :D
     
  7. Just my luck...
    Not a single octave in that page...:(


    Note to self: build EH BMS. :D

    Here's a schem for an Octave/Fuzz ( works well )
    Those transistors are Germanium pnp, but you should be able to use any PNP silicon transistor with a gain of around 80 - 100.
    You could change it to NPN if you reverse the voltage supply and the polarised components.
     
  9. I still haven't found a nice, low octave pedal...
    cmon...:rolleyes:

    one problem being... now that I am in the wiser, it would be e BIG build - plus waaaaay more expensive to build an octave... thay have some CRAZY chips in them...

  11. If I was into building an octave down effect, this would be the one.

    It's reported to track very well. The circuit is designed so that the divided (octave) signal dies out at a slightly faster rate than the note you're playing. So, the divided signal simply dissapears just before the point where you would start to hear the sputtering that is typical of other, poorly tracking octave effects.

    Plus, the components sould be relatively easy to get your hands on. :)
