How to build an effects pedal for fuzzy synth/organ sounds.
The Erratic Clutch Deluxe is a unique effect pedal that gives you fuzzy square wave distortion as well as a
monophonic sub-octave square wave using a total of only four transistors. The two signals can be used
individually or mixed together for a raw synthy output. Full of character and quirk, this pedal will give you
a truly original sound.
Warning: This circuit was designed for use with a 9 VDC power supply only.

  • Page 5 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 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.

    **This build guide uses a lot of right angle bends. This is so the instructions are not only legible but it also helps to keep leads from shorting since multiple components will be stacked on top of each other. The right angles are not necessary as long as you make sure that no leads are shorted.** SECTION 1 Please refer to DRAWING 1 and DRAWING 2.
  • Page 8 SECTION 2 Please refer to DRAWING 3.  Strip and tin a ¾” piece of wire and connect the lug 3 on the footswitch to lug 9 on the footswitch. Solder both connections now.  Strip ½” of insulation off of the end of a piece of wire. First tin then snip the exposed wire from the rest of the wire.
  • Page 9  Strip and tin a 2 ½” piece of wire and connect the positive lug of DC power jack to bottom hole at #13. Solder the both connections now.  Connect a 56k resistor from #7 to #11 using the bottom holes POSITIVE for both connections.
  • Page 10 SECTION 5 Please refer to DRAWING 6.  Connect a 330pF capacitor from #7 to #11.  Connect a 330pF capacitor from #6 to #10. Be careful not to short these two capacitors.  Connect the 680k resistor from #19 to lug 1 of the left 100KA pot. Solder both connections now.
