I bought a masterbuilt strat and found out that the neck relief at each side of the string(1st, 6th) is different. When I set the neck relief at 6th string 0.010", the neck relief at 1st string 0.022". Also at the 6th string side, 9~12th fret is higher that neighboring frets so it looks like it is backbowed at 9~12th fret while the whole neck is slightly upbowed. I thought that this is defective product but the dealer told me it is very normal and it doesn't violate fender's quality control. Can't believe fender assure the 0.012" difference between neck relief of each side of the neck, also twisted at 9~12th fret, consider it is 6000$+ instrument. Any idea about that?
