Organizing Wire, Connecting Volume Pots and Switch

Guitar Circuit Wiring Electronics, Video 51

Here is part 3 of the video series on wiring up guitar electronics.

In this video, I talk about how to lay out wires in a semi-hollow body so they aren’t ugly through the f-holes, using shrink wrap tubing to keep things organized. I also show how to connect a volume pot, soldering the braided shield of a wire to the back of a volume pot that already has other wires connected to it (using needle nose pliers as a hold-down). Lastly, I start wiring up the switch, and show what to do if you’ve lost track in the tubes of which wires are which. If your multi-meter doesn’t have continuity mode (beeps when a connection is made), you can just use resistance mode and look for connections on 0 resistance. Another idea to avoid confusion is to use different colored wires for each volume pot, or try to label them before running them through the tubes.

I’m trying to wire up a switch and I’m a little confused. It’s a
switchcraft LP style switch and it has 5 little prongs. I’m just wiring two
pickups and it would be great if you could help me figure out the
connections.

You don’t need to get an official Gibson branded one, if that’s what you
mean. Those are pricey. Switchcraft makes good replacements at about half
the price. Be sure to open up the guitar to check the style of the switch.
I believe SG’s require a right-angle switch. For example, Switchcraft part
number EP-4365-000

hey thanks for all these helpful videos! i’m putting two humbuckers in my
guitar and need a 3-way pickup selector. All of the wiring diagrams i’ve
seen show 3 prongs coming off the 3-way pickup selector, but the only 3-way
switches i can find have 4 prongs on them. How would i go about wiring this?

Hi, um I need to replace pots for my Epiphone Les Paul… it has four pots.
Where would I buy these.. and would you recommend I do this myself or
should I find a professional I have no soldering experience whatsoever D:

You’ll need to balance the cost for tools (like soldering iron, pliers,
etc) and energy/time to practice and learn, versus paying a guitar tech to
do the work. If you think you’ll do more electronics projects later, then
this is a great chance to get started! You can find pots at many online
stores, like allparts, guitarfetish, guitarpartsresource, and electronics
sources like mouser and digikey. And you can sometimes find them in-store
at GC. Good luck!

Sounds like a fun project! Look at the wiring diagrams at the
guitarelectronics website. There’s several diagrams for HB/SC/HB with one
vol and one tone. There’s many other diagrams there you can refer to for
ideas. Good luck!

If you want to DIY, you’ll need to learn some fundamentals. You’ll need to
read a book or two. But learning by experimentation is really key for good
understanding. I have some good beginner’s book and resource
recommendations in the FAQ at my blog. Good luck!

The only thing i’ve done prior to this is a switch from a single coil to a
humbucker on a strat, which I did by studying the existing wiring and
working it out. I have a guitar with the HB/SC/HB set up like the one I
want on my custom, should I just wire it the same way?

You could use the same pots as in your other guitar, if you’re happy with
them. See my other vids on selecting and understanding pots, tapers, etc.

great stuff ! i am installing a telecaster alnico bridge pickup. it has a
blue wire and yellow wire. on the blue wire there is a tab. does that get
grounded to the body or the bridge ? thanks.

it just kind of loops off of the pickup and has a tab on it. so i screwed
it to the body. but the rest of the blue wire continues to the controls
where i soldered it to the pot. sound right?

I’m having trouble wiring up my 3-way switch

It has four lugs on each side of the wafer, I can’t refer to my old switch as it’s a completely different one heh

I’m looking at the wiring diagrams and they show one wire, from any of the pots, and they split to connect to one lug on switchseach side. For example a wire leading from the left most lug of a volume pot, splits, and connects to the very top right lug and very bottom left lug on the switch. Is this a hot and ground wire being connected?

For short runs of wire, it’s not so important. But you should try to use
shielded wire for longer runs.

When soldering to the switch, would I solder the braded shield to the top lug? In my diagram, the top lug is running to ground, so is that where the braded shield would connect?

  @wombweasel222 – yes, replacing a volume pot with a switch is simple from a wiring perspective. a volume pot is ground on one side and signal on the other, with the output in the middle. Using a SPDT switch, wire it exactly the same way (ground on one side, signal on other, output in the middle). with the switch on one side, your output is tied to ground (like having the pot turned down to 0). and with the switch on the other side, you’re pickup is connected directly to the output.

  @wombweasel222 You may be interested to know there is a product by Shadow called a “kill-pot.” It is a pot that also works as a kill switch when pushed in like a button. I have one on my strat copy and find it very cool. I guess you’d need two on a Les Paul or you could somehow make it a master volume, as I plan to do with my LP one day.

sorry im starting on this, ive noticed that pots and the pickup selector have various lugs, how do you know exactly which one you should conect with? thanks for the help! 🙂

  March 14, 2011 @ 11:35 pm
  
  @mxzvt – best thing you can do is use a multimeter, in resistance mode. hold the two multimeter leads to two of the lugs, and move the pot or flip the switch. then try two other lugs, etc. map it out, and soon you’ll understand what’s connected to what in each switch or pot position. if you don’t have a multimeter, at least buy an inexpensive one. you won’t regret it!

    @johnplanetz I measured my 500k pots with a multimeter on the 200kohm setting and it showed 14.5. What does this mean? I held the negative lead to the lug which was grounded and the hot lead to the center lug.

      @MitjaShi – see my video “Potentiometers – How They Work, Disassembly and Exploration”. You need to measure across the two outer lugs to get the overall pot value. if you measure from center lug to outer lug, you’re seeing the resistance based on the current shaft position. Also, if you’re measuring the pot in-place in the circuit, there may be interactions with the other circuit components.

  @KIDWICKED369 – if you’re confused about how a switch works, take a multimeter and test for each switch position, which lugs are connected together. It’ll become very obvious, very quickly 🙂 If you’re looking for diagrams, search for “Les Paul Switch Wiring” and you should find some resources. There’s also the guitar wiring diagram archive at the guitarelectronics website.

Hi John, as you know on a 2 volume and 2 tone guitar you can decide to make the wiring chosing how to wire the volume controls, independent from each other or having only a master volume when the 3 way selector switch is in the middle position.
I heard the 2 ways of wiring may have different sound result, is it true or is a misconception? Thanx!

  @krisjingle – Sounds like a simple wiring error. Don’t be disheartened- it’s totally normal to make a few mistakes. Just double/triple check each wire connection against your diagram and make sure everything’s where it’s supposed to be. If you want some more diagrams for reference, see the wiring diagram archive at guitarelectronics . com. Also, I often suggest that it’s very useful to connect everything up with alligator leads before soldering to make sure you understand the circuit.

I’m using 22 gauge shielded wire…just wondering if you could solder the shielded wire and the striped wire together and then solder it to the lugs of the pots,reason why is because the wire under the shield is very thin once stripped from the rubber.
if this is done would it cancel out any noise eliminating properties that the shielded wire has?

Reply
- John
  February 28, 2012 @ 9:28 am
  
  @megatron804 – no, you should not solder the shield to the inner wire. Use the shield as the ground return, and the inner wire as the signal. As long as the inner wire is sound (you didn’t accidentally cut into it while stripping off its cover), you should be fine. Don’t worry about its thinness.

In another video i watched, it was about making your own instrument cable they soldered the copper shield to the 1/4 inch jack, and here you are soldering it to the back of the volume pot, why not just cut it off?

Reply
- John
  October 24, 2012 @ 9:00 pm
  
  In the instrument cable, the shield is being used as the return/ground. If you are not using the braided shield as the return, you could snip it off – and it may still provide some resistance to EMI noise. But it’s better to connect it to ground, so any EMI noise the shield picks up will be conducted to ground.

This may be a stupid question but, I need to wire up this guitar I’ve made. I have all the components and a wiring diagram came with it. Is it now simply a matter of looking at the diagram and soldering every thing together? or is there more to it that isn’t displayed on the wiring diagram?

  I guess it depends on the wiring diagram, but yes- that is essentially what you need to do. You might benefit from also looking at the wiring diagrams at the “guitar electronics wiring diagram archive”. These are very complete diagrams.
  Find the configuration that matches your guitar, and compare. That should give you a better comfort level going forward.

  I don’t know how much a shop would charge to do a complete guitar-build. Probably more than you’d want to spend, but I suppose it depends on the shop, the tech, the guitar, and your location. Unless you’re buying a kit, aftermarket pickups do not come with pots – you need to buy them separately.
