I recently purchased a Willy Wolf Super End Pin stop, which I thought was a really cool idea. Unfortunately, the end pin on my Kay upright is far too large to fit in the sleeve. In the past I've used a tennis ball with a slit in it jammed over the end pin. This method works great, with one flaw: I have a dog who is absolutely OBSESSED with all things tennis ball. He will not leave it alone. You can see how this might end up badly for the bass (and possibly the dog). I've tried spray painting the tennis ball black, but I'm not fooling the dog. Are there any similar things on the market to the Willy Wolf Super End Pin?
Woof.
