One holiday, I took out my guitar which I hadn’t played in a long time, connected the shield, and when I tried to play it, there was an unusual noise from the amplifier. Noise was being generated, and the sound cut in and out.
At this rate, the entertainment factor drops.
Electronic parts used in electric guitars, such as pots and jacks, are consumable parts that deteriorate over time.
Guitars and bass jacks that have not been used for a long time, will rust and this noise will be particularly prone to occur.
I checked my guitar jack immediately!

The nuts are corroded and I can't tell if they were gold parts or what.
I removed the plate and checked the jack inside.

The corners of the terminals were rusted.
The part where the tip of the shield contacts was also worn and the color had changed.
I could try and repair it by removing the rust, but this time I decided it was time to replace it because it is a consumable part.
Click here for the jack to use this time!

Pure Tone Jack is a phone jack that is used for replacing conventional monaural phone jacks, which usually holds the plug with only one hot terminal at the tip. The Pure Tone Jack increases this to four terminals: hot terminal x2 and ground terminal x2.
In addition to improving the strengths of the connection of the phone plug, the phone jack can also transmit signals more efficiently as it is designed along the round shape of the plug, making the contact area with the plug larger.
The difference is obvious at a glance when you line it up with the SWITCHCRAFT jack that had been installed before.


So let's actually install the pot.

The terminal circled in red is hot and the terminal circled in blue is ground.
The arrangement of this pin is the same as that of SWITCHCRAFT.
At the time of replacement, it’s not necessary to cut the wiring again. It can be connected as is, and I think that it is a very carefully designed feature (The wiring in the image uses a shielded wire)


There’s one nut and one washer to attach the jack.
Depending on the thickness of where the part is to be installed, replacement may be completed faster if you prepare a nut for adjusting the length below together with a chrysanthemum washer to prevent loosening.


When the replacement work is completed and the shield is inserted, you can feel the firm hold and feel at ease.
Also, I think that the treble is slightly better with the new jack.
As this procedure is simple, it took me only 15 minutes. So if you are considering replacing the jack, please try this out!
