Wiring up the Jack

Guitar Circuit Wiring Electronics, Epiphone Riviera P93, Jack, Video 55

This is part 5 of the video series on wiring up guitar electronics.

In this video, I show how to wire up the jack. I’m replacing the original Epiphone jack with a Switchcraft L12A. The L in the part number indicates a longer 3/8” bushing, which is just a bit longer than the Epi jack. I’m hoping this well allow me to fit a lock washer in addition to the regular washer and nut, so the jack will stay tightly in place rather than falling into the body of the guitar so much (as I showed in my Don’t Know Jack video).

I also demonstrate how to use a multi-meter to identify which lug should be ground, and which should be signal. My meter is a Mastech MS8229. If your meter doesn’t have continuity mode (beeps whenever a connection is made), you can just use resistance mode and look for 0 resistance to indicate a connection. Note the L12A has a third, middle shunt lug, which you can just ignore.

@frg8526 Yes, that should be a great iron for the kind of work you’ll be
doing. Have fun!

Hey just a quick question. those black wires you’re using, with the ground
braided around the signal, where did you get them? At my electronics store,
they only have patch cables which are too thick to work with. thanks again!

So if ones the ground and ons the signal..whats the middle one ? can I use
a jack with 2 lugs for a microphone with pot?

Do u kno what color the signal wire on a schecter damian6 is?Black or
white…I think I mixed em up??Signal always goes to the tip right??I put
the black wire to the tip and white to sleeve,it seems to work but I want
to make sure its right…I guess I could take the cover off the back and
see what wire goes to the pot or lug right??

how do you find out which is the ground/hot connector without that machine?
I’m installing a pickupwith a white and red wire and have no clue

Wow, is mine really Different…..My jack gets a seperate free wire that runs from a solder puddle on the Bridge Pot to the Sleeve/ground connector. And my Tip or HOT Output gets a free seperate wire that leads from the middle connecton of the 3 Way Switch, thats actually two posts on the 3 way pushed together to the Output Jack connector and thats all. DOES THIS MAKE ANY SENSE TO YOU???? Im reading from the Seymour Duncan Diagram in their Slash PUs I purchased and that doesnt work too well

@Davesintexas – sure that makes sense. there’s many ways to wire up a
guitar circuit, and lots of different pickup/tone/volume combinations. i’m
showing just one possible way here, for my Riviera P93 (three pickups,
three volume knobs and a tone knob). sounds like your guitar has 2 or 3
pickups, a three way switch, and no tone knob? take a look at the
guitarelectronics wiring diagram archive for more examples.

hey i am in the middle of building a guitar and i have the pickups in place, i attached the fretboard, and the tuning nobs
all i have left is to wire up the rest of it and put in the volume knobs and ect.
problem is im only 16 and i have 0 experiance soldering or using wires. is this something i can figure out by watching youtube videos and following them or should i just pay 50$ to have someone wire it for me?

@miguel4756 – it’s unlikely that your jack needs to be replaced. it’s
probably just a broken solder connection. you can easily repair it, but
you’ll need a soldering iron. a cheap one from radioshack,etc will do.
you’ll also need some 60/40 rosin core solder. just resolder those wires,
referring to these videos for tips and get a wiring diagram if you need one
from the guitarelectronics Guitar Diagram Archive. it’s not hard- and
you’ll improve quickly with experience. good luck!

so my ground cable got disconnected on my jack there still alot of solder on the jack its self, should i dis solder or can i heat it and run the cable through, never have solder/dis soldered before also my jacks kinda lose would you recommend replacing it all together and if so what jack? thanks in advance

  @Nelson123n – it’s generally a good idea to remove the solder on the lug using a solder sucker, so you can clean off any stray wires from your broken connection. If you don’t have a solder sucker, you can try heating it up and pushing your new wire through, but it can be hard to see what you’re doing and line up the wire properly. For a loose jack, try adding an inner-tooth lock washer between the nut and the regular washer.

Do you have to have the shielded wire to run from the jack to the pot? Could I just use two regular hook up wires?

  @dashizzler – regular wire should be fine for short cable runs. Shielded wire becomes more important for long runs, to avoid picking up noise.

why do you attach the jack wire to the tone pot? why not the volume pots

Reply
- John
  October 4, 2011 @ 10:08 am
  
  @Berserkaroid – in this circuit, one side of the middle volume pot is connected to the tone pot. The lug on the tone pot here is electrically identical to the lug on the middle volume pot. and the tone pot is closer to the jack, so that’s the better place to hook it up. For this guitar’s wiring diagram, see my planetz blog post “Riviera P93 Circuit Wiring” on 9/21/2009.

  @GuitarBoyA7X most basses ive owned and im sure it will be the same for guitars have had a ground wire running from the bridge to one of the pots, the pots then grounded onto each other and the pickups grounded onto the pots i am no expert but so i maybe wrong hopefully someone else will have more info

Do any of the GROUND wires need to be Shielded?? doesnt Just the hot leads need to be sheilded??? can someone plz answer this

Reply

  December 1, 2011 @ 8:16 am
  
  @97warlock – right. you can think of the shield as another wire- used to carry the ground/return. So for a pickup, the shield of the signal wire is used for the pickup’s ground connection. If you have a ground wire- like to your bridge, it doesn’t need to be a shielded wire.

on a different note:On a solid state amp …….if theres loud HISS when its cranked ………guitar volume down ….and unplug the guitar & still loud hiss, then unplug the cord from the amp & have dead silence…….what does that mean?

Reply
- John
  December 2, 2011 @ 3:17 pm
  
  @97warlock – some hiss is typical at high gain. The amount depends on the amp. The input jack is probably switched, which is why the amp completely cuts out when you have nothing plugged in.

  @DoctorSess – you have to remove the electronics through the f-hole. It’s not fun 🙂 See the other videos in my channel for how to do that, and how to get them back in- also not fun!

  @DoctorSess I recommend using either string to tie to the pots, or aquarium pump tubing that fits around the pot shaft snugly. It’s a little bit more difficult, but not bad if you know that trick.

there are a few diffrent kinds of jack normaly open normaly closed and mono or stereo most guitars are mono the one in video is and its normaly closed its more used for power amps what that dose is ground audio hot to ground to shut up the hiss or hum u get from most amps when its inserted it disconects the ground from audio hot and alows the signal to flow into preamp stage of an amp

  Easy. An SG has a backplate. Unscrew it for access to the electronics and resolder the wire to the jack. And be thankful it’s not a hollowbody!

nice video u got there. i have a problem. hope u can solve it. im still new in soldering components. what happens is i just solder the jack connector without knowing which one is ground wire and which one is for the signal. Im using a strat guitar and the problem is my guitar has lot of noise especially the 2nd and 4th switch… is that the reason why my guitar has lot of noise?

  There’s no point in guessing the wire identity- you should buy an inexpensive multimeter (like $5) so you can learn which wire is which.

Just a pointer. You don’t melt the solder to the iron to apply to the component. You heat the component with the iron and apply solder to the hot component. 1 this ensures that the item is hot enough for the solder to bond, avoiding a cold solder (bad connection). 2 solder will flow in the direction of the heat. This makes the solder flow in and around wires to make better connection.

Reply

  March 20, 2013 @ 3:07 pm
  
  The bridge stud should be connected to a ground point- e.g. the back of a pot or one of the pot lugs, etc. Ultimately all grounds must be connected to the lug of the jack that connects to the sleeve of the guitar cable.

  You’ll be fine. Use a multimeter as I demonstrated at 0:48 to identify which lugs are connected to the plug tip/sleeve. Your extra lugs are probably switched lugs (only connected when the plug in inserted) – these are useful in a pedal for completing the battery circuit only when a plug is inserted, to save your battery when the plug is removed.

Great vid! I have a question. I was wiring a jack socket, but before i soldered, i was gonna check the sound. (this was for a home made pedalboard). there was a “noisy” sound before i even had plugged the guitar in. I tried putting the jack from the amp directly to the effect pedal without going through the jack socket i was wiring, and the noise was gone. so the problem was between the socket and the wire. any idea what it can be? please answer. 🙂

  A jack doesn’t typically introduce noise. Were you using alligator clips, or holding the wire in place by hand? Alligator clip leads are typically unshielded and long and can pick up some noise. Did the problem go away when you soldered it?

It’s still a lot of sound when the guitar is not plugged in, but when the guitar is in, it’s all gone. Thinking it might be like when a jack cable is not plugged in the guitar.

  Get a multimeter (even a cheap $5 one will suffice), and follow the steps I show at 0:48 to identify the lugs on your jack. That, and a wiring diagram (e.g. from the guitarelectronics wiring diagram archive) will be everything you need.
