You can figure out the combo like Glen said. *
Since it is a brand new guitar and you seem unsure how to go about the nut work, I would take it back to where you bought it and either A) get another one or B) have them fix it at no charge. *
I'm a DIY'er at heart but I had some
high frets on my DBK when I got it, I went as far as marking them with a marker and took it back to the store and made them fix it. *They were really cool about it, needless to say it wasn't a GC or any other superstore. *
I can understand some problems slipping through QC every once in a while, Ibz seems to have more than it should sometimes, however, there is no reason you should have to live with them on your new guitar.
Also remember that if you take a file to a new guitar and screw it up your warranty is null and void. *
If it is a used guitar and you are unsure of doing the work it should be easy to find a competent luthier in the Atlanta area. *Spending the bucks on someone who knows what they are doing could save you some heartache. *Not to mention that experience is invaluable, sometimes the problem is something different than you think it is and someone with more experience can point it out to you. *
Like I said, I'm very much a DIY'er but, if you are unsure about what to do, start by learning to setup a guitar really well and know what to look for before taking files to one. *I did end up having to take a file to my LPE on my DBK 'cause the knife edges weren't sharp at all but I had the problem narrowed down to that before I got out the tools. *If you go to a luthier ask him questions and see if he will show you some tips and tricks. *From personal experience, I've learned alot and made friends with some luthiers and it has really paid off.
