Ernie Ball 4040 Poly Strap Red

I picked it because of noticeable color and almost the lowest price, and I can honestly say, that can it get's job done for. Still it has some drawbacks, especially if you're thinking of using it on heavier guitars like the Les Paul, because in such a case, the force will pull the strap into the neck, where it rubs against the skin, which is not the most pleasant. It's not that annoying, but after several hours on the shoulder, it can definitely itch, so think about how much time you plan on playing with it. Also for SG guitars, I would suggest a leather strap, as this is made of slippery plastic, so won't reduce neck-dives, if your guitar has it. The holes at the ends are small enough so that the guitar does not fall, otherwise they are also easy to enlarge with a sharp knife.
