I agree with Henryb, if you tinker with it they have every right to put the blame back on to you. You should take it back to them immediately or if you cannot get back for a day or two phone them and let them know the problem and when you will be taking it in.

I would have thought any store wanting to keep it's good reputataion would either fix it immediately for you or alternatively loan you a replacement whilst the remedial work is completed so I suggest you ask if they offer either service.

You could try taking a "very small" piece of paper and folding it a time or two and place it underneath the string at the top of the neck...that should raise it just enough to keep it from buzzing.....

I recently got the action on my acoustic guitar lowered, and it was great for a few weeks. Now, I hear a buzzing, or twanging (if that makes sense) from the thinnest (e) string. From what I have read, it's likely because the string is too low and is touching the fret. When I play a chord with that string open (C), it's horrible... if I play a chord where I'm touching that string (G or D), it's fine.

Before I go back to the store, my question is: is there any way to correct this myself? (I know the store will want to keep my guitar for about a week, and I'd like to avoid that, but if I have to leave it, I will.)

Thanks for any suggestions.
