Hm, vrat ne bi smeo da bude potpuno prav, tj. imace grozan fretbuzz, tako da ako je potpuno prav treba popustiti trussrod da vrat dobije malo bow-a, tj. da se poveca relief. A ovo za podesavanje MM gitara/bas gitara je iz pera Big Poppa-e licno, tj. Sterling Ball-a. MM je malo specifican jer koristi vintage one-way trussrod, a i oni su jaaaako ponosni na svoj factory setup i insistiraju da se akcija (barem manja podesavanja) ovako doteruje
Ja sam doduse svojevremeno malo podigao zice i na bridge-u jer nisam bas fan Petrucci-evog ultra-low setup-a, ali za sve ostalo 1/4 kruga truss-a sve resava. Genijalno...
First check relief in the neck by holding the lowest string down on the 2nd fret with your fretting (left) hand. Then, hold the same string down on the 12th fret with your plucking thumb and tap on the string in the middle to see how straight the neck is. There should be no more than the thickness of a business card between the string and the frets. If there is no relief in the neck, a little pressure in the middle of the neck (after adjusting the trussrod wheel) should help.
The standard string gauge is .45-.100 with a .130 on the low "B" for the 5 string at 440 tuning. If you decide to tune down, typically you would increase the gauge for every 1/2 step downward that you tune. This will keep most of the measurements close by having more tension on the neck.
Factory String heights are: Bass side 3/32 to 7/64 Treble side: 5/64" to 7/64" from the top of the 12th fret to the bottom of the string. The rest of the strings should have the radius of the fretboard when looking at the top of the string, (with the A string hidden from view by the E string, etc.), rotating the bass at the same time. The "right" string height is, of course, ultimately determined by your playing style.
The pickup should be 4/32" to 5/32" on the bass side and slightly closer (4/32" to 5/32" on the treble side. This is determined by tuning and volume of strings measured by the top of the pole piece to the bottom of the strings. If the G string needs more volume, adjust it slightly more toward the pickup. Again, if you tune down, more distance is needed here, as well; but in any case, no lower than 4/32".
If fret buzz occurs from the open to the fifth fret, the neck needs more relief. If it buzzes between the 5th fret and the 12th fret, the neck needs to be straighter (turn the wheel slightly clockwise). If it occurs all over the neck, the string height need to increase (by turning the trussrod wheel slightly counter-clockwise).
For intonation: Check the harmonics to the fretted note on the 12th note on the twelfth fret if you don't play much above that fret. If you do, also check the harmonics at the 19th fret after the 12th fret is set. If the fretted note is sharp, you need to make the string longer by turning the saddle screw counterclockwise, and vice versa. Make sure that the string are coming off of the saddle straight and not in an arch. All measurements must be rechecked after each adjustment.
