Title: Adapting a 3 band tone control into 3 different fuzz circuits
Post by: mordechai on June 07, 2010, 11:22:43 PM
Hi,

I found the following schematic (take a look):

Would it be possible to have each channel go into its own fuzz circuit (like the Anderton Quadrafuzz but perhaps a simpler concept) and then recombine as pictured here?

  Duncans Tone Stack Calculator...amazing tool, download it for interactive, knob turnin', graphic display watching, frequency/amplitude tellin' 'empowering toy'..fun to play with, watch the lines move, notice/note the changes...that "upthere" means higher amplitude [more output].
  Try your favorite tonestack.
  The link shown has 1 channel, made 3 times, each with a Fuzz input to drive, a mixer for each of the preEQ'd fuzz outputs [3>1 mixer or better] will work.
  Alternatively, take a look at parametric EQ, and bandpass Filters.
  Fuzz eq. options include before and after Fuzz, amp, and speaker.

Short answer:  No.  The circuit you show cannot provide separate outputs.

Thank you for the clarification Mark.  How would you suggest building a circuit where the signal is split into low, mid, and high separate bands, then each run through their own fuzz before reconnecting to the output?  I'm more interested in volume control for each band, with all then running through the same fuzz level control.

I have looked at the Anderton Quadrafuzz and it seems far more involved than what I would like to accomplish, and I'm having trouble isolating the parts in the schematic that would be useful to me.
