I have a Yamaha Pacifica 012 which I have had since this morning. It has two single coil pickups and a humbucker. The single coil ones are level with the strings and the top of the guitar but the humbucker is tilted from front to back i.e the end nearest to the neck is higher than the end nearest to the tail of the guitar. Is this normal? There seems to be no way of adjusting it if it is wrong. I put this same question on another forum and it appears that there is nothing that can be done about it. Is this true?
If so, should I send it back for a replacement?

Thanks in anticipation

Brian
