Great quality!! Clear sound and cable stays put Review: Great guitar jacks - I use these TRS jacks in mono configuration on electric guitars. The ring is wired to the sleeve (ground), and the tip connected normally. This provides a more solid connection to the plug, to prevent it pulling out, thanks to the fact you now have -two- spring elements in the jack holding on to the plug, rather than just one, as in a typical mono jack. The extra connector also provides a more positive connection to the ground-sleeve of the plug, which can reduce noise caused by a flaky ground connection. And Switchcraft quality is legendary. ## Features - Made in USA, - Switchcraft Type 12B (Pack of 2) - Nickel Plated - 1/4" Female Input Jack - 3 Conductors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06Y2BR5MY | | Best Sellers Rank | #233 in Stereo Jack Cables | | Brand Name | Switchcraft | | Cable Type | AUX | | Color | Nickel | | Compatible Devices | Musical Instruments, Amplifiers, Audio Mixers | | Compatible Phone Models | Compatible with older phone models with 1/4 inch headphone jack | | Connector Gender | Male-to-Female | | Connector Type | 1/4 Inch Jack | | Customer Package Type | Protective Packaging | | Customer Reviews | 4.8 4.8 out of 5 stars (311) | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Shape | Round | | Manufacturer | Switchcraft | | Maximum Voltage | 10 Volts | | Model | 8541722636 | | Model Name | Switchcraft 12B | | Number of Items | 2 | | Number of Pins | 3 | | Other Special Features of the Product | Long Bushing, Chassis Mount | | Outer Material | Nickel | | Recommended Uses For Product | audio equipment connection | | Specification Met | RoHS | | UPC | 609722127103 | | Unit Count | 2 Count | ## Product Details - **Brand:** Switchcraft - **Cable Type:** AUX - **Compatible Devices:** Musical Instruments, Amplifiers, Audio Mixers - **Connector Type:** 1/4 Inch Jack - **Special Feature:** Long Bushing, Chassis Mount ## Images ![Type 12B (Pack of 2) Stereo 3-Conductor Input Jack, 1/4", Double Open Circuit, Made in USA - Image 1](https://m.media-amazon.com/images/I/81IkX51I8eL.jpg) ## Questions & Answers **Q: What are the dimensions of jack? The "package" dimensions are listed but one doesn't install the package.** A: The dimensions are in the pics of the product. Everything is right there! Seriously! Right There!!! **Q: used in a stereo amp will these disconnect the speakers when headphones are plugged in? Like a switching jack.** A: Only if you wire your speakers through this jack. **Q: will this be able to shut off main speaker when the earphone is plugged in?** A: No I do not think these will work for your application. I'm guessing that you want to be able to practice your guitar amp at home without the noise affecting your family. Go to your nearest Guitar Repair Center tell them what you need and I guarantee they will have one and they're usually not that expensive and not that difficult to install ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great sound *by K***S on July 17, 2025* Good fit and stay good!
