  • Page 6: Completed Example

    Your finished build will look something like this. Don’t be alarmed if some of the components are different colors. As long as they are the correct values, they will work just fine.

  • Page 7: Populating The Circuit Board

    Populating the Circuit Board STEP 1: Add the diodes. Be sure to match the striped end of the diode with the stripe to the layout on the PCB. The stripped end should go in the square solder pad.
  • Page 8 STEP 2: Add the resistors. Resistors are not polarized, so it does not matter which end goes in which solder pad.
  • Page 9 STEP 4: Add the film and ceramic capacitors. These are not polarized so they can be inserted into the PCB in either direction. The capacitor highlighted in yellow is the ceramic disc...
  • Page 10 STEP 5: Add the transistors. Orient the transistors so that the flat side matches up with the flat side of the PCB layout. Be sure to put the 2N5089 in the space highlighted in yellow, the 3904’s in the spaces highlighted in blue and the 2N5458's in the spaces highlighted in red.
  • Page 11 Step 6: Add the two DIP8 IC sockets. Only solder the sockets to the board. The ICs themselves will go into the sockets. Orient the sockets to the notch on the PCB lines up with the notch on the sockets. When installing the ICs, match the notch on the body with the notch on the PCB.
  • Page 12 Step 7: Add the trimpots. There are three legs on the trimpot, but 5 holes on the PCB. This is to allow for the use of various sizes of trimpots. Your trimpots will fit into three of them nicely. When you are done with your build, you will need to adjust the trimpots before your build will work properly.
  • Page 13 STEP 8: Add the aluminum electrolytic capacitors. These are polarized. The positive end will have a longer lead and should go in the square solder pad. The negative end will have a shorter lead with a black strip running down the body of the capacitor.
  • Page 14 Step 9: Add the battery snap. Thread the solder ends of the battery snap into the strain relief holes from the bottom solderside of the PCB and out through the top. Insert the solder ends of the battery snap wires into the topside of their respective solder pads. Solder on the bottom side of the PCB.
  • Page 15 Step 10: Add wires to the OUT, Ground, and RING eyelets. Start by cutting three 2.5 inch pieces of wire and two 6 inch pieces of wire, set aside the 6 inch pieces for now. Strip ¼ inch off each 2.5 inch piece and tin the ends. Tinning means to apply some solder to the stripped ends of the wires.

  • Page 16: Main Pcb Assembly

    Assembly Step 1: Flip the PCB over so that the bottom or solder side is up. Insert the B100k dual gang (DEPTH), C100K (SPEED) potentiometers, and the LED into the bottom side of the PCB. DO NOT SOLDER YET!!! The LED will have one lead that is longer than the other.
  • Page 17 Step 2: 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 and LED all go into their respective holes.
  • Page 18 Step 5: Install the DC jack into the enclosure. Connect the TIP (negative) terminal of the DC jack to the “-“ eyelet on the PCB with 1 inch of hook-up wire. Connect the SLEEVE of the DC adapter jack to the “+” eyelet on the right side of the PCB with 1 inch of hook- up wire.

  • Page 19: Wiring The Jacks

    Wiring the jacks Step 1: Install the enclosed jacks into the enclosure. Be sure to ‘clock’ the jacks. In other words, make sure to orient them in such a way that the solder terminals of the jacks don’t come into contact with anything they’re not supposed to. Any orientation will work, as long as you are mindful of the terminal designations as shown above.
  • Page 20 Step 2: Connect the three 2.5 inch pre stripped and tinned wires to the enclosed jacks.

  • Page 21: Footswitch Assembly

    Footswitch Wiring/Assembly There are no actual number markings on the footswitch. Orient the footswitch so that the flat sides of the solder lugs are running horizontally, not vertically. There is no "top side" or "bottom side" of the switch until you actually solder something to it and designate it as such.
  • Page 22 Step 2: Take one of the 6 inch pieces of wire from earlier and strip about 1.5 inches from one side. Run the striped end between lugs 4 and 9. Solder both lugs. Be careful not to short the bare metal striped end against any other lugs on the footswitch.
  • Page 23 Step 3: Install the footswitch into the enclosure. Remember to place the footswitch lock washer on the inside of the enclosure to help prevent spinning. You can choose to use the nylon washer on the outside if you’d like, it helps reduce damage to the finish while tightening the outside nut, but it’s not absolutely necessary.
  • Page 24 Step 4: Cut and tin four 2.5 inch wires. These will be for lugs 1, 2, 5, and 7. Once they are cut and tinned, insert them into the eyelets on the PCB and solder. You can remove the footswitch from the enclosure for more space if you need.
  • Page 25 Step 5: Connect the short wires to their respective lugs on the footswitch. Refer to the information above about the lug numbers if you are unsure about the number scheme of footswitches.
  • Page 26 Step 6: Add the second 6 inch piece of wire from the earlier steps to lug 8 of the footswitch. You will notice that both wires at lug 4 and lug 8 aren’t connected to anything else yet. Those will be our final connections.
  • Page 27 Step 7: Connect the wire from lug 4 to the INPUT jack TIP terminal, connect the wire from lug 8 to the OUTPUT jack TIP terminal. It’s okay to leave the wire a little long to allow for movement of the wire if needed.

  • Page 29: Operation Overview

    Operating Overview SPEED: Controls the speed of the tremolo effect. CCW is a slower effect, CW is a faster effect. DEPTH: Controls the depth of the tremolo effect. CCW is a shallower depth, CW is a deeper depth. POWER: 9V Battery or 2.1mm tip-negative wall adapter.
