How to Fix the Input Jack on a Bass Guitar
Dec 11, · Jason shows to fix minor wiring issues on his Warwick Corvette Bass. how can i fix my bass guitars electronics wiring? I have a disconnected jack and ground wires that need sorting Answered I have a bass with some wires lose in its wiring. the output jack has come off- there is a red wire and a white wire going to it, i know where the red wire goes because that came off whilst i was fiddling, i presume the white.
I have a bass with some wires lose in its wiring. Also as well as the red and white there was two bare ground wires that had snapped off inside the heatshrink, where should they be connected to?
Also the ground wire that goes under the bridge is lose, i need to know where that goes. Hopefully the pictures will help you imagine the situation a little better, as i haven't described it very well. Thanks to anyone who helps. Best Answer 11 years ago. A photo of the entire wiring harness including the pickups would be helpful.
OK--now I see you wrote below you have two pickups. That helps, but complicates matters. Also, the color of the wires isn't that important-- if we can't see what they are connected to.
There should be color standards for guitar how to fix bass guitar wiring, but there aren't any. The color may be helpful; for instance if both pickups are identical. So a wider scope photo would be great. Is there a pickup selector switch?
We can't guess this information And what does this mean? Are the red and white wires shielded? What does "the heatshrink" refer to? Given all that, there is a lot you can deduce: -- The grounded wires for your guitar will always share a common connection somewhere in the guitar.
So the ground for the bridge will connect to the other grounds. It's best to connect them together at a single point called a star ground. Those will be ground connections, also utilizing the POT case as a shield. I can see I haven't really helped you much, but there are many variation of pickup wiring. Without seeing more of the harness, that's about all I can do Answer 11 years ago. As you can see on the nearest contact pad on the volume POT there is a red wire this is the wire i was referring to erlier, soldered to the top of that POT is the ground wire soldered that you can just see on the far side of the volume POT.
On the right is the tone POT, again on the closest contact you can see the white wire i mentioned erlier on. Well, that helps--some. A single, clear, inclusive photo would also show relative wire lengths, which can be a helpful clue. If so, which ones? Re: "heatshrink"--I know what heatshrink is, I still don't know what "the heatshrink" refers to in your context Is it: -- the insulator on a shielded cable?
You claim it's unimportant, but that two wires have "snapped off" inside? Sorry, I can't reconcile those two conflicting facts broken connections--that don't matter. Or picture it from your description It was likely there for a reason. I can see some things: What are the ingredients in candles two pickups are wired together in series.
They appear to be connected to the volume POT via a Blue shielded cable. My guess which is based on limited "intel" : -- Both the Red and White wires connect together on the signal tab of the output jack. Both POTs are grounded via the far tabs, the ones you couldn't see or the one furthest from the red wire on the volume POT and the white wire on the tone POT and vise versa. The signal wire from pickups is soldered to the centre tab on volume POT No, none of the POT tabs are soldered to each other, just the end ones soldered to the housing.
Sorry, the heatshrink bundle the red, white and two ground wires together leading off towards the jack connector. I didn't mean that the wires weren't improtant i meant that the actual heatshrink doesn't directly affect the circuit.
You won't see the heatshrink because i had to cut it off to reveal why i could see four wires going into the heatshrink tubing but only see two coming out. And from what i can see myself it looks like the bridge ground was simply connected to the same output jack tab as the other grounds. I how to make your own board game instructions know enough about guitar electronics in particular how to achieve goals essay know how to stop corruption in pakistan essay that could be correct or not.
Hey, no biggie. With the POT tabs grounded as you describe, the White wire can't be a ground --the tone control would be connected to GND at both ends, and do nothing. Since you know the White wire leads to the jack, it must connect with the Red wire on the "tip. Doesn't matter whether the bridge ground is connected directly to the jack GND or what is mobi format books the volume POT can--either way, it's grounded.
I was just trying to account for the unused "blob" on the POT. If you think that wire is routed directly to the jack, you're probably right. But either way would be identical on a schematic. How the grounds are connected together can have a large effect on noise, however. Not that no-name guitar manufacturers paid much attention to that Yeah i might extend the bridge ground to the pot, would tidy things up near the jack, but the blob of solder doesn't have anthing snapped off in it but that's besides the point.
Is the ground connection on the jack the one anti-clockwise from the big long tip connector? It's tough to tell from the photos, but one of those tabs will be directly connected to the "ring" that encloses the shaft of the plug. That's the ground. In the second photo in the original posting at topit sure looks like the bottom tab is the ground tab. You should be able to visually trace the metal parts, and where they connect in the jack. If not, time to buy a cheapo VOM volt-ohm meter at Walmart, and use the ohmmeter as a "continuity tester.
Stereo requires three connections right, left, groundand a TRS plug and jack. The White wire connects directly to the Red because that's the way tone controls work--they "shunt" high frequencies away from the signal, through the capacitor on the tone POT, and away to the ground. Does that sound like a good plan? It's a plan. You'll never get a signal without a ground, though.
All electrical circuits need a "return path" for current. The ground for bridge, however, is ONLY for noise suppression. When the bridge is connected to the ground, your body acts as a shield that's why your guitar is quieter when you're touching the strings So if "sorting out the ground" refers only to the bridge, then you're good Good luck, BTW.
I got it to work, thanks for all your help, i just got it working and teted it and it worked then i snapped another wire and thought, rigght ok back to the soldering iron all i gotta do now i find screws to replace the ones that are missing. Any ideas what the type of screw is that alters the pickup height cause they aren't normal screws? I lost a screw which holds the cog onto the tuning peg, and i'm sure it can't have been there for a while otherwise i would have picked it up when i heard the cog fall off.
Cool--rock on, man. Missing screws: if you're extremely lucky, you might find some replacements at a real hardware store not a chain. In my experience, the screws on musical instruments are always a weird diameter or thread pitch, though. It's more likely you'll have to go to a music store for that stuff. I've got a bucket of old hardware from "totaled" guitars, but I still have to hit the stores to find stuff periodically.
Google "bass guitar wiring" and you will get some sites to get you started. Add the name of your guitar and my might find the exact schematic for your guitar. Since you didn't give it I can't try it myself. How to prepare carrot halwa in pressure cooker many pickups? Any on guitar controls? It is very possible that the white and grounds all came off the same connection but impossible to tell from here.
I did try googling it couldn't find one similar to mine and i can't google the guitar name because i don't know it! It is quite an old guitar with no name, maker or model printed anywhere on it, i suspect it was just a cheapo thing when new.
It has two pickups, a volume control and tone control. Follow Asked by mdog93 in Living. Tags: guitar bass music bass guitar wiring amp jack pickup bridge tuning.

The ground eventually gets pinned to the ring of the phone jack.
Jul 23, · My bass was sounding horrible, so I had a go at fixing it. Took me a while but eventually figured out what to do!Author: Nerd On The Wire. Clean the jack with rubbing alcohol or blow it off with compressed air to remove debris. Solder any loose wires that may be affecting the sound of your bass. Plug the soldering iron into the outlet and allow it to warm up. Place the hot tip on the metal and place the solder directly onto the hot metal to secure the solder joint.
The so-called "input" jack of a guitar is actually an output jack that sends the signal from the pickups out to the amplifier. Over time, the jack itself can become loose or the wires that are connected to it can become loose as well. While replacing the jack is a simple solution, it can also be fixed, saving you the time of the replacement.
If one or more wires is disconnected, they can be re-soldered and if the contacts are dirty or loose, they can be cleaned and adjusted as well. Plug the bass guitar into an amp and the set the volume very low, just enough to hear the signal. Wiggle the cord around and try to find the spots that sound crackly or intermittent. If there is no sound when the cable is plugged in, push it in hard or pull it out slightly until you hear a signal.
These actions may help you understand what is wrong with the input jack. Remove the jack plate or control cavity cover of the bass. Jazz basses require that you unscrew the whole jack plate to access the input jack, while other types allow you to easily access the input jack in the control cavity.
Visually inspect the wires going to the jack as well as the jack itself for any loose connections that may be apparent. Clean the jack with rubbing alcohol or blow it off with compressed air to remove debris. Solder any loose wires that may be affecting the sound of your bass. Plug the soldering iron into the outlet and allow it to warm up.
Place the hot tip on the metal and place the solder directly onto the hot metal to secure the solder joint. Remove the tip of the soldering iron and the solder, placing the soldering iron on its holder to prevent burns to the work table.
Check the input jack to see if that made an improvement. Use a pair of pliers to bend or move the contacts of the input jack. Over time, the contacts can loosen or move out of position causing intermittent or no sound from the bass. Rather than replacing the jack, bend the contacts back into place so that the connection is strong once again. Bend it until it looks as though the tip of the cable is touching the tip of the contact of the input jack. This will only work on non-bullet style jacks.
Replace the jack by removing the solder from the broken jack and unscrewing it from the bass guitar. Wire the new jack using the same wires from the pots and screw the jack back into place. Plug in your bass to an amplifier to ensure that your soldering work is sufficient.
If it is still scratchy, it may be something other then the input jack that is the problem. Christian Mullen is a graduate from the University of Central Florida with a bachelor's degree in finance.
