The New York Pro is a chinese mandolin. It goes by several names, Bestler, Johnson, NYP, etc.. I've seen about 5 or 6 names on the same instrument. I've got a Bestler, and did a little homework.
As for the set up. The nut is cut high, and the bridge needs to be shaved. Not the feet of the bridge, but the riser saddle. The string grooves on the nut benefit from a light rubbing with a ultra fine grit paper. This will help with any string popping you may be experiencing. I had a problem with the 10th fret on the 'G' side of the board. I just dressed and leveled the frets and all is well. There are several articles on reseting the nut. For starters, hold down the 'G' between the 2 & 3 frets and look at the distance between the string and the first fret. You should set the nut height so that the string is close, but not touching, the 1st fret. I like mine as close as possible, but low setups invite buzzzz. And, if you haven't replaced the strings, I would suggest you do that imediately. The ones that came with is are junk. Best suggestion, go buy two new sets of strings, and take it to get a good setup. The tech will set it up and put the strings on for you. This will be the best thing you could do for yourself. Plus, that poor mando hasn't been loved or pampered since it was created. No care or consideration. Cut, slap, glue, next. So, any care and pampering you give it will come back to you 10 fold. Think about it. Buy a rich girl a diamond necklace, and she puts it in with the other jewelry, and you get a hug. If your lucky, a kiss. Buy a poor girl a diamond necklace, and you just won the lottery.
(Please forgive any status/sexist references. I think of all my instruments as different people. Some are poor men, one or two are a rich mistress.)
Give me a B Flat. Ah, just give me a B and i'll flatten it myself.
