Thanks for the advice. I always stretch my strings when I put them on first-thing, so I don't think it is that. I'll have to take it to the music shop I guess, or maybe try new strings. I really don't think I had this problem before this set of strings. Or maybe I'll just play it and avoid hammer-ons for now. I'll let you know if I find out anything.
