- Page 5 The essential tools are all the bare minimum of what I use to build a pedal. The list is not exhaustive, but we do get a lot of enquiries about what tools people need. I sell a large range of pedal building related tools here. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...

- Page 7 If you want any further explanation about how to decode resistor values, this video may help. There’s also a lovely table below to use as a starting point. NB, whilst most values I use are shown there is a chance not all will be. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 8 1% resistors tend to have blue bodies. 5% buff. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 9 Aim for a maximum of 4 seconds. Less is good! If you have more than one diode to solder it is good practice to do one leg on each then go back for the second. This way the diode has time to cool between each leg being soldered. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 10 Through hole Jfet’s are becoming globally scarce. Therefore, I have gone to the effort of creating the ‘Jed Fet’. A pre-soldered SMD Jfet J201, on its own tiny board which you then join to the PCB using © Jeds Peds truebypass@jedspeds.co.uk...

- Page 12 Now the bad news. they come in a variety of shapes and sizes and although there are supposed to be standards for markings they do vary. So, what do they look like? This kit predominantly contains box caps, like this one. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 13 On the capacitor you will see that one side of the can is marked with a stripe usually containing negative symbols. The wire nearest to this is the negative wire. You will also notice that the positive wire is longer. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 14 Working in height order mount the rest of the parts to the PCB ensuring that you solder them in place well as you go. I then add the pots either mounting them to the board or wiring them into place. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 15 Sometimes they don’t. If the pots you receive don’t have the dust cover, then you need to ensure you isolate the metal case of the pot from touching any other metal components, or it will cause you problems. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 16 They are too tightly packed in to fit. Therefore… make sure you leave a gap between the board and the rear of the unprotected pot to prevent shorts. Now connect the pots as shown above. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 17 The above is for centre negative power supplies. Should you have the opposite you must reverse the connections. At this stage, connect two long wires to the socket as shown and set it aside. There is no need to put anything in the enclosure just yet. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 18 Take one wire from one tip and solder it to the IN pad. This is now your test phase input jack. Take the final tip wire and solder it to the OU pad. This is now your test phase output jack. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 19 If your PCB is working you are ready to connect the board to the footswitch! Follow the next stages meticulously and all being well by the end of it you will have a lovely finished pedal! © Jeds Peds truebypass@jedspeds.co.uk...
- Page 20 About 2 inches long will be perfect, a little longer if you wish. They will be cut to length later. Cut the ground joint and strip the ends of all wires again so they are fresh. The PCB should have 4 wires coming from it all about 5/6 inches long. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 21 As you can see, there are some parts on the footswitch board too, some on each side. Small faces out, tall faces in. See how it says Faces in? That’s a tactful hint from me to you. That side of the board faces inside the case further instructions read the note below it! © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 22 If you put them in vertically… you’ve done it wrong. So be careful please. The switches can go in on a 180-degree axis, don’t forget there is no ‘pin 1’ © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 23 Start working through these connections by mounting the main pcb inside the enclosure as well as the other offboard components. Then one by one make the appropriate connections ensuring you use appropriate wire lengths. You do not want a rats nest. © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
- Page 24 Just make sure you connect like to like. If it does not work and you can’t spot an error, don’t forget we have the Facebook forum to guide you. Good Luck and happy soldering Love Jed x © Jeds Peds truebypass@jedspeds.co.uk OnoSecond...
