How to build an effects pedal for fuzz with non-selective frequency tripler.
The Contortionist II kit is an all analog, high octane fuzz box. It produces fuzz with layered octave
overtones similar to those produced by an electronic-bow. The frequency multiplier circuitry creates
harmonics that swell and recede depending on gain setting, pick attack, neck position and pickup. This is a
high gain circuit that can put out up to 2 volts and will provide ample amounts of sustain.
Added features to the original contortionist circuit include a tone control and LED.
Warning: This circuit was designed for use with a 9 VDC power supply only.

  • Page 5: Final Assembly Reference Drawing

    FINAL ASSEMBLY REFERENCE DRAWING This is a large version of the final assembly drawing. Refer to this drawing as you make your way through each step of the instructions. Before you make a new connection at a particular terminal or solder lug, notice how many other connections will be made at that terminal. That way you can decide whether it’s best for you to solder the connection and leave space open for future connections or hold off on soldering until after every connection at that location has been made.

  • Page 6: Soldering Tips

    SOLDERING TIPS It is important to make a good solder joint at each connection point. A cold solder joint is a connection that may look connected but is actually disconnected or intermittently connected. (A cold solder joint can keep your project from working.) Follow these tips to make a good solder joint.

  • Page 8: Section 3 - Mount Components To Terminal Strips

    Please note that each terminal has been numbered as illustrated here and will be referred to as a “terminal #_” when connecting different components and wires throughout the assembly instructions. Strip and tin a 2" piece of wire and connect footswitch lug 8 to the output jack's tip lug.
  • Page 9 Connect the 0.1µF cap to terminals #2 and #4. This should be mounted upside down to allow room for other components to be mounted later in the instructions. There will be two more components connected to terminal #4 so do not solder at #4, yet. Connect the 3M resistor to terminals #4 and #5.

  • Page 10: Section 4 - Finishing Up

    Locate the battery snap connector. Connect its red wire to the power jack's "positive switch" lug and connect its black wire to the input jack's ring lug POSITIVE-SWITCH LUG SECTION 4 – Finishing Up It’s always a good idea to thoroughly double-check your connections before applying power. This will minimize the risk of damaging components.
