EHX Hogs Foot

Request

  1. thanks for posting this up so quick, it is built and verified! i'm still playing around with the transistors, and so far the higher gain ones sound better to my ear. cool little circuit. it sounds like it cuts treble as much as boosts bass. has kind of a funky sound. i like it. quick and easy build, as well. thanks again

    1. That's great thanks for that. Yes I think with this being made for bass it doesn't really care about the higher frequencies, but it makes a nice alternative to the Screaming Bird.

  2. Cool... hey maybe throw the bird and the hog in one box?

    1. Yes, it'd be interesting to see how they interact with each other. Or if you've got any 4PDT toggles you could have a single board and switch between Screaming Bird and Hogs Foot mode.

  3. How can we eliminate the popping sound with pedal is being engaged? I tried a 1M pulldown resistor but did not do anything? Please help,
    Thanks

    1. Try smaller value for pulldown.. Where did you connect it?
      +m

  4. verified. built myself a "bad piggy" bass boost from this circuit. I am getting an intermittent pop when engaging it. where should I connect the pulldown resistor?

    1. Put a 1M resistor anywhere you can fit it between the 2nd and 4th rows. It could be the LED causing the pop though (assuming you're using one of course), in which case you'll have to do something like this: http://www.muzique.com/lab/led.htm

    2. Thanks, I suspect it is the LED, I'm using a common cathode bicolour to indicate on (green) and off (orange). I'll put the RC network on and see if that helps. Looks like it's a good idea anyway

  5. I ran out of 3.3uf electrolytic caps and 43k resistors, but have plenty 2.2uf and 47k resistors. If I sub one each one respectively, how will it affect the circuit sound wise?

  6. i need a volume boost after a distortion (bass through guitar fx, low output from it) and a bass boost would be welcome, does this circuit boosts volume as well?

    1. it does, but it will also remove nearly all the high end, due to the low pass filter created by the 27k resistor and 100nF cap to ground at the input, and the 100nF from collector to +9v boosts the low end. i've build one and ended up socketing them, so i could try different values until i got something i liked. by the time i was done it ended up being more of a transparent bass boost that gives just a nudge of lowend.

  7. logarithmic potentiometer is not?
