Page 6: Populating The Circuit Board
Populating the Circuit Board Step 1: Add all the resistors. Resistors are not polarized and can be inserted in either direction. - Page 7 Add the transistor sockets sockets. ONLY SOLDER THE Step 2: SOCKET! The sockets get soldered to the PCB. The transistors get inserted into the sockets. The actual transistors never get soldered. You will insert the transistors into the sockets after the entire pedal has been built. Match the tabs on the sockets to the tabs on the tabs on the PCB screenprint.
- Page 8 Step 3: Add the trimpot. There are 5 holes on the PCB, but only three leads on the trimpot. Do not be alarmed by this, this is to accommodate different trimpot sizes. Your trimpot will fit neatly into three of the five holes. Once you have installed your transistors, adjust the bias trimpot to taste.
- Page 9 Step 4: Add the film capacitors. These are non-polarized so it can go in either direction.
- Page 10 Step 5: Add the electrolytic capacitors. These ARE polarized, meaning there is a positive and negative end. The positive end will have a little groove in the body, like the screenprint outline.
- Page 11 Step 6: Add the battery snap. Thread the solder ends of the battery snap through the strain relief holes from the bottom solder side 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.
- Page 12 Step 7: Add wires to the IN, OUT, RING, and two Ground eyelets. Start by cutting four 2.5” pieces of wire, and four 1.5” piece. Strip 1/4” off each end and tin the ends. Tinning means to apply some solder to the stripped ends of the wires. This keeps the strands from fraying and primes the wire for soldering.

Page 13: Main Pcb 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 14 SOLDER ANYTHING YET!!! The LED will have one lead that is longer than the other. THIS WILL GO INTO THE SQUARE SOLDER HOLE.
- Page 15 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 and LED all go into their respective holes.

Wiring Step 6: Connect the TIP (negative) terminal of the DC adaptor jack to the eyelet on the PCB labeled “-“. Connect the SLEEVE of the DC adaptor jack to the eyelet on the PCB labeled “+” farthest to the right. Connect the battery disconnect terminal of the DC adaptor jack to the second eyelet on the PCB labeled “+”... - Page 17 Stereo (input) Jack Mono (output) Jack Step 1: Install the 1/4” jacks to the enclosure.
- Page 18 Step 2: Install the footswitch. Orient the footswitch so that the flat sides of the solder lugs are like the diagram below. NOTE: There are no actual number markings on the footswitch. There are two correct ways you can orient the footswitch. They are both 180 degrees of each other.
- Page 19 FOOT SWITCH SOLDER LUG DESIGNATIONS Step 3: Wiring the foot switch. Make a jumper between lugs 3 & 6 from clippings from the resistors. • Simply use your needle nose pliers to make a U shape & insert into lugs 3 &...
- Page 20 Cut two 1” pieces of wire. Strip 1/8” off each end and tin. These will • be used to connect lugs/eyelets 1 & 7 Cut three 1.25” pieces of wire. Strip 1/8” off each end and tin. This • will be used to connect lugs/eyelets 2, 5, & 8 Step 4: Install the foot switch into the enclosure if it isn’t already.
- Page 21 eyelet goes to the tip of the stereo jack. The wire from the RING eyelet goes to the ring of the stereo jack. The wire from the eyelet closest to the stereo ê jack goes to the sleeve of the stereo jack. The wire from the OUT eyelet goes to the tip of the mono jack.
- Page 22 Finishing Touches Add the OC75 transistors to their sockets. DO NOT SOLDER THEM!!!!!!!! DO NOT CLIP THEIR LEADS!!!!!!!!!!! Soldering or clipping them will void your warranty. We will not accept returns is they are used. Install your transistors into their sockets with full leads to test the pedal first. When you know that your pedal works and sounds the way you expect it to, then clip the leads and re-install the transistors.
