Mono Guitar Output Jack, 1/4-Inch
Product description
Key points
Four contact points are the main difference here: the jack is designed to hold a standard 1/4-inch plug more securely than a two-contact design. That larger contact area may help create a steadier connection when a plug gets moved during playing or setup.
You get three mono output jacks, each with nut, washer, and mounting components. The jack part is brass, while the nuts and washers are iron, the finish is gold. They’re intended for guitars, basses, amplifiers, pedals, pedal boards, and other audio equipment that uses a matching mono jack.

For a repair, this set gives you spares rather than a single replacement. It’s also a possible upgrade when an existing jack is old or damaged. The four-contact design is a specific connection feature, though it should not be read as a guarantee of quieter sound in every instrument or setup.
How to use it


These are replacement or build components, not a plug-in accessory. Installation means mounting a jack in compatible equipment and connecting it as part of the instrument or audio circuit. The included nuts and washers support mounting, but the listing does not specify installation instructions or tools, so the work may call for basic electronics know-how.

Keep in mind that no jack dimensions or mounting-hole measurements are provided. Check the space and opening on your guitar, bass, or audio equipment before choosing it, the 1/4-inch figure describes the plug size, not the jack’s full mounting dimensions. From the way it is set up, the four contacts are intended to improve plug retention and contact area, but they won’t correct unrelated wiring or signal problems.
Practical tips
If a guitar’s output cuts in and out when the cable shifts, a worn or loose jack is one possible part to inspect. This three-pack could suit a repair bench or a player who wants replacements on hand, as well as someone building compatible audio equipment. It’s less suited to a quick fix if you’re looking for a fully wired assembly rather than a component that needs installation.

Before fitting one, compare the existing jack’s connection and mounting arrangement with the replacement. Also confirm that the equipment uses a mono jack and a standard 1/4-inch plug. A solid pick if you need several mono jacks for compatible repairs or builds and value the stated four-contact design. It might not be a great match if you need confirmed fit dimensions or a no-installation replacement.


Questions before you buy
How many jacks are included? The package contains three 1/4-inch mono output jacks, with nuts, washers, and mounting components.

What are the jack and mounting parts made of? The jack part is brass, the nut and washer are iron. The listed finish is gold.
Will it work with a standard 1/4-inch plug? It is described as mating with standard 1/4-inch plugs. Confirm that your equipment also calls for a mono jack and that the mounting arrangement fits.
Should you buy it?
This set makes sense when you need multiple mono output jacks for repairs, builds, or replacing old or broken parts, and the four-contact layout is relevant to your setup. The included mounting hardware is useful, but it doesn’t establish that the jack will fit a particular instrument: mounting dimensions aren’t listed. Choose it when you can verify the fit and are prepared to install a component, look for a fully specified or prewired replacement if you need a more direct swap.
