My friend just invented this clever product for guitarists with shoulder/neck/back issues. It is a belt strap, instead of going over the shoulder (though there is a shoulder version too). Two years ago, I broke my neck in a cycling accident, and was fully paralyzed from the neck down. Thanks to good luck, and great doctors, I am back walking again, and playing bass. However, my left shoulder and arm are still very weak, so standing to play has been a challenge because of the strap pressure. I recently played my first live show since my accident, and I had to sit while playing to get through the performance. I switched from a Warwick Thumb 5 to a 4 string P and a Dingwall ABZ5 to get lighter instruments. I've also been on a buying rampage of lighter amps/cabs to help with loading in/out. While those changes have been helpful, this has the most powerful direct impact on my ability to play live shows. I just got the hip/belt strap and it feels great to stand and play bass without the instrument weight being a hinderance. I though I would share, since I doubt I'm the first guy to have neck and shoulder issues. http://slingerstraps.com/ https://www.facebook.com/SlingerStraps Slinger Straps "Hip Strap" Guitar Strap - YouTube Sorry if this is a bit spammy, and/or in the wrong sub-forum (mods, please redirect to a better place if needed).
