Many years ago, one of the music stores in town used to have a rack full of Ernie Ball Polypro straps in every color. Above the rack was a picture of Eric Clapton with his trademark Stratocaster and a Polypro. The caption read: “If it’s good enough for Eric, it’s good enough for you. 59 crowns including tax.” I would tend to agree. On a more philosophical note, it is simple and unadorned enough that it doesn’t distract from the guitar, instead it recedes into the background and keeps your instrument and what your hands are doing with it in the foreground. On a more practical note, it is a guitar strap, period. It does what it should do and does so at a bargain-basement price.
I used Polypros for a couple of years, mostly because they were long enough back when DiMarzio’s straps weren’t. It doesn’t have so much to do with trying to look cool as the simple fact that I am 200 cm (6’7″) tall and straps are made for guitar players of average height. I loved the feel and the simplicity of the design. I still enjoy the straps greatly, but since I got back to the ClipLocks, my Polypros live with my acoustic guitars. For me personally, that just works better. There is nothing wrong the Polypro per se, it was just that I got tired about worrying about them in a live setting. I used those little twisty strap locks, but they started popping off during shows and I had to go hunt for them during the breaks. (I kept forgetting to bring spares.) On a Fender, you get a bit of extra security because of the way the strap wraps around the top horn. On a Les Paul, the tension pulls away from the strap lug, which is a recipe for… unexpected things.
