    Parts Checklist for The Lazy Sprocket Kit Resistors: 1 - 390ohm (orange/white/black/black/brown) 1 - 470ohm (yellow/purple/black/black/brown) 3 - 1k (brown/black/black/brown/brown) 1 - 3.3k (orange/orang/black/brown/brown) 3 - 4.7k (yellow/purple/black/brown/brown) 3 - 10k (brown/black/black/red/brown) 3 - 22k (red/red/black/red/brown) 1 - 47k (yellow/purple/black/red/brown)

  • Page 6: Populating The Circuit Board

    Populating the Circuit Board Step 1: Add all the resistors. Resistors are not polarized, so they can face in either direction.
  • Page 7 Step 2: Add the diodes. The smaller 1N914 are highlighted in red. The larger zener is highlighted in yellow. Make sure the black stripe on each diode matches with the stripe on the layout.
  • Page 8 Step 3: Add the IC socket. Match up the u-shaped notch in the socket with the notch on the layout. If the op amp that is supplied with your kit does not have a notch in it, there will be a small dot in one corner. This denotes pin #1.
  • Page 9 Step 4: Add the trimpot. When you are finished with your build, adjusting this trimpot will be very important. When you set the trimpot, you want to have the attack knob turned full turn clockwise so that it should produce the slowest swell.
  • Page 10 Step 5: Add the transistors. The 2N3904s are highlighted in red. The 2N5457 is highlighted in yellow. Make sure that the transistors' curved sides and flat sides match the layout. Using a SK30 JFET: If you wanted to use an SK30 JFET, the PCB has eyelets to accommodate this.
  • Page 11 Step 6: Add the film caps. These are not polarized and can go in either direction.
  • Page 12 Step 7: Add the electrolytic capacitors. These are polarized, meaning they have a positive and negative end. The positive end of the cap will have a longer lead and should go in the square solder pad.
  • Page 13 Step 8: Add the battery snap. Thread the wires of the battery snap through the holes in the PCB before soldering as shown below.

  • Page 14: Assembly

    Main PCB Assembly Step 1: Mount the AC adapter jack to the enclosure. Your kit may come with either an external thread or internal thread. Don’t get confused by this. They still function exactly the same. You just thread the external nut on the outside and the internal nut on the inside.
  • Page 15 Step 2: Flip the PCB over so that the bottom or solder side is up. Insert the four potentiometers, toggle switch and the LEDs into the bottom side of the PCB. DO NOT SOLDER ANYTHING YET!!! The LED will have one lead that is longer than the other. THIS WILL GO INTO THE SQUARE SOLDER HOLE.
  • Page 16 Step 3: Hold the PCB in one hand so that the component side of the PCB is in the palm of your hand and the bottom side with the pots, toggle switch and LED is facing up. Now use your other hand to guide the predrilled enclosure onto the PCB assembly so that the pots, toggle switch and LED all go into their respective holes.

    WIRING Step 6: Connect the TIP (negative) terminal of the DC adapter jack to the eyelet on the PCB labeled “-“. Connect the SLEEVE of the DC adapter jack to the eyelet on the PCB labeled “+” farthest to the right. Connect the battery disconnect terminal of the DC adapter jack to the second eyelet on the PCB labeled “+”...
  • Page 18 You will want to place the jacks into the enclosure so the sleeve terminal is facing the right like the picture above. Be sure to remember the lock washers so the jacks don’t spin on their own. Step 7: Install the footswitch. Orient the footswitch so that the flat sides of the solder lugs are like the diagram below.
  • Page 19 FOOT SWITCH SOLDER LUG DESIGNATIONS Step 8: Insert the foot switch wires into their respective eyelets on the PCB. You can insert them into the top side and solder on the top side as well. The solder pads should be large enough (if you are using a soldering iron that isn’t too big) to allow you to do this without burning the PVC coating on the wires if you are careful.

  • Page 21: Finish Up

    Installing IC/Finish up Don't forget to add the knobs, put the cover on the enclosure, and apply the bumpers to the cover.

  • Page 22: Operating Overview

    Operating Overview ATTACK: Controls the speed of the effect. CCW is a slower swell effect; CW is a faster swell effect. SENSITIVITY: Controls the sensitivity of the effect, or how much signal must be present to trigger the swell effect. CCW requires a stronger signal to trigger the swell effect;...
