Made in the USA with durable materials and backed by a satisfaction guarantee, this system ensures your guitar stays safely strapped so you can focus on your performance. ## Description Product description Strap Jack is the best way to keep your acoustic-electric guitar securely strapped on when playing unplugged—preventing your strap from slipping off and protecting your guitar from falling. Strap Jack is simple, easy to use, works with all acoustic-electric guitars, requires no modification to your instrument. Why do I need it? If you play an acoustic-electric guitar, you know that putting your strap on is difficult because the endpin jack is bigger than the strap hole. And since the strap fits poorly, it can slip off—dangerous when you’re playing unplugged and there’s no instrument cable to catch your guitar. Strap Jack solves this problem and protects your guitar by keeping your strap securely in place. How It Works Simply attach your guitar strap to the endpin jack of your acoustic-electric guitar and plug Strap Jack in. Attach the other end of your strap and slip the rubber washer over the front strap pin. Strap Jack is a system designed to keep your strap securely in place while you play your guitar unplugged. Do I need to alter my guitar in order to use Strap Jack? No. Strap Jack works with your acoustic-electric guitar’s existing factory installed or aftermarket endpin jack. How is Strap Jack different from ordinary strap locks? Strap Jack requires no modification to your guitar, unlike other strap lock systems that must be permanently installed on your guitar and strap, and require that the endpin be replaced. Strap Jack is a single piece that’s simple to install and remove, and is not permanently attached to either your guitar or your strap (which makes it easy to use one strap with multiple guitars, unlike strap locks). Review: Perfect for acoustic when you are not plugged in - Bought this for an acoustic guitar with a K&K pick up. If I was not plugging the guitar in, then I was worried about the strap possibly slipping off the end pin jack. So now i put the strap on as usual and then insert the Strap Jack to be sure the strap stays in place. Works great and I no longer worry about my guitar falling. Review: Perfect solution for my Martin - I just opened the bag and tried this thing out and it fits into the pickup of my D-28 solidly and securely. I first unscrewed and removed the little nut adapter to reveal the bare screw which provided a lot more space and a much narrower stem for my chunky strap to hang onto. I took a photo of this with the strapjack in place before putting the strap on it, you can see there's a good 1/4" of stem visible. Then I put the strap on there (why strap makers don't make these holes a little bit less bulky I do not know...there's no reason for it to be quite so thick, but that is another issue) and inserted the strapjack, it clicked in with that same satisfying "click" just as your cables do, no doubt that it's in there and it isn't going anywhere. ## Features - Plugs In To The Output Jack Of Your Acoustic - Electric Guitar When You're Unplugged - Works On All Acoustic - Electric Guitars - Fits All Brands Of Guitars - Buy a separate Strap Jack for each of your guitars and keep it in the case - Satisfaction Guarantee - Made In the USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N76AZKR | | Body Material | Wood | | Brand | Strap Jack | | Brand Name | Strap Jack | | Color | Black | | Connector Type | 1/4" jack | | Customer Reviews | 4.5 out of 5 stars 53 Reviews | | Finish Type | Painted | | Global Trade Identification Number | 00636134554951 | | Included Components | Case | | Item Dimensions | 2 x 1 x 1 inches | | Item dimensions L x W x H | 2 x 1 x 1 inches | | Manufacturer | Strap Jack | | Model Name | SJ-2 | | Model Number | SJ-2 | | Part Number | SJ-2 | | UPC | 636134554951 | | Unit Count | 1.0 Count | ## Product Details - **Body Material:** Wood - **Brand:** Strap Jack - **Color:** Black - **Item dimensions L x W x H:** 2 x 1 x 1 inches - **Model Name:** SJ-2 ## Images ![Guitar Strap Lock System For Acoustic - Electric Guitars (2 Pack) - Image 1](https://m.media-amazon.com/images/I/71yktibUcaL.jpg) ![Guitar Strap Lock System For Acoustic - Electric Guitars (2 Pack) - Image 2](https://m.media-amazon.com/images/I/71Q4Wv7hx4L.jpg) ![Guitar Strap Lock System For Acoustic - Electric Guitars (2 Pack) - Image 3](https://m.media-amazon.com/images/I/6173vFh6XiL.jpg) ![Guitar Strap Lock System For Acoustic - Electric Guitars (2 Pack) - Image 4](https://m.media-amazon.com/images/I/71iOARQDC1L.jpg) ![Guitar Strap Lock System For Acoustic - Electric Guitars (2 Pack) - Image 5](https://m.media-amazon.com/images/I/81D8QlGT55L.jpg) ## Questions & Answers **Q: Will plugging this in to an acoustic-electric guitar with an active pickup drain the battery?** A: It drains the battery on my Taylor 314CE guitar. I stopped using it because of this. **Q: Still confused if this will drain an active system or not?** A: It will 100% drain a battery on a Taylor 314CE **Q: Does it work with a k&k pure mini end pin jack?** A: If it is a 1/4-inch output jack, then yes, it will work with that system. **Q: I'm thinking about getting this to protect the jack on my travel acoustic. Is the jack easily removable even if I don't have a strap attached?** A: This works great....but only if u have an acoustic electric where the cable plugs in to the end pin... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for acoustic when you are not plugged in *by L***N on November 19, 2024* Bought this for an acoustic guitar with a K&K pick up. If I was not plugging the guitar in, then I was worried about the strap possibly slipping off the end pin jack. So now i put the strap on as usual and then insert the Strap Jack to be sure the strap stays in place. Works great and I no longer worry about my guitar falling. ### ⭐⭐⭐⭐⭐ Perfect solution for my Martin *by M***I on August 19, 2019* I just opened the bag and tried this thing out and it fits into the pickup of my D-28 solidly and securely. I first unscrewed and removed the little nut adapter to reveal the bare screw which provided a lot more space and a much narrower stem for my chunky strap to hang onto.

Just be careful because it might drain your battery. Not sure how to check which guitars it does that on... --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/44577877-guitar-strap-lock-system-for-acoustic-electric-guitars-2-pack](https://www.desertcart.co.uk/products/44577877-guitar-strap-lock-system-for-acoustic-electric-guitars-2-pack) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
