Greetings. My purchase of the Greco Beatle Bass came with a strap. But this strap is a real cheapie and does not stay on the knobs. (It is an accident waiting to happen.) So, I certainly don't need an expensive strap, but I was wondering while I am considering a strap, what should I look for? It seems like I need the kind that has some kind of ties that could be tied to the knobs?? I am not really looking for a list of brands, but more about what style you like and why. I know this question probably sounds a bit trite, but actually I am interested in knowing what works for you. Thanks so kindly.
