Parasit Studios Eagle Claw

Fuzz Friday! Freppo over at Parasit Studios makes some insanely cool stuff. Here's his Eagle Claw octave fuzz. You can probably squeeze it into a 1590a if you're feeling adventurous. In his own words:

The Eagle Claw is simple yet brutal, noisy and glitchy sounding CMOS-based fuzz with a full wave rectifier to produce a strong octave up. This circuit works best with high output pickups. It is a gated circuit by nature of the CMOS logic. If you are using single coils and need more sustain, try a boost or compressor in front. To bring out the strongest octave up, use the neck pickup on your guitar with the tone rolled down. The octave is most intense around the 10th fret and higher.

    Built it and works, same as the video's sound, cool~
    please tag it and thanks for the layout~

    so glad to built this because I just fail from the 'Phantom Octave'. .hehe
    thanks again~

    I love your designs! But let me make some minor observations about them:

    1) Closed ground planes or vias might act as loop antennas. Though you might not notice it in a simple analog 9v circuit, it's a good habit to leave some little space unconnected in the ground plane to avoid loop antennas.

    2) Square pads should be reserved for: pins 1 of ICs and pots, 9v+ power rail, capacitors +, and diode/LED cathodes.

    Besides that, your designs are truly perfect. Keep up the great work!

    Just built mine into a 1590A using the transfer layout. Works great. needed a couple more ground pads but i drilled my own. Also, you forgot to reverse the text in at least the original transfer pdf

      Check Parasit Studio's info on it, but I think you need the unbuffered UBE chip.

    Hello! Really love this site, it's amazing!
    I'm trying to build this pedal but I have a question (it's my first time, so I'm a complete noob)
    On the General Layout Notes I see the diagram for Off board wiring but I see two Grounds on the circuit board and here's only one. Where should I put the second one? Or else I don't know how to connect the board to the DC Jack and the Output jack.
    And one more question, where's Out?

    Hope you can help me with this!! Thank you so much!
