Or is he talking pegs as in tuning machines? In which case it's the nut......Really doesn't matter though....Take it to someone who knows what they're doing. Saddle, nut, neck relief...all that stuff? If you don't know what the "thingies" are why in the hell did ou think you could fix it?At least try to read some of the info at Frets.Com before you try any other home repairs.
