Hi, I just tired going to 10 gauge strings from 9 gauge and when the music shop put the new strings on they had to make some minor intonation adjustments to my start. I don't like the feel of the 10s now that I have been playing them for a few days so I am going back to 9s. I want to just do the re-string myself. Will the intonation be off when I go back to 9s? Or can I just re-string with the 9s and not expect an intonation problem?

The intonation should be checked and, if necessary, adjusted for the lighter gauge strings.

If the switch from 9's to 10's meant that the intonation (probably the truss rod, too - etc.) needed adjusting, my bet is that it happens again when that switch is reversed.

Anyway, I think every guitar player should know the basics, so read this Strat SetUp Guide and start learning.

Yes , Intonation and trussrod check.

For truss rod ,you need to wait few days .

Yeah I need to learn all of it: how to re-string, intonate, adjust string height...as I am tired of driving to my guitar guy once a month and putting money in his pocket. Usually only a change in gauge affects intonation? Does string type? All the adds for EB Cobalts have caught my eye and I may try them.

Restring may change intonation and neck bow ( truss rod ) , not always , you have to check .

Neck bow may take few days to move .

Action never change with any type of string .

There are few good books and video about guitar work . It is not a rocket science.

This is dead wrong, and bad misinformation.

The action varies with the sum of the tension of all the strings.
The tension of each string depends on three things: the tuning frequency, the distance between nut and bridge saddle for that particular string (adjusted scale length), and the mass of the tensioned length of string between nut and bridge.
The latter varies not only based on string diameter, but also the string's elasticity and the string material's density.

Because different materials, alloys and windings have different densities, changing from a nickel or nickel/steel to an iron/cobalt string with the exact same diameters can change the tension, and thus the action.

An example, without even changing brands:
D'Addario .042 strings tuned to E, tensions, 25.5" scale length:
XL - Nickel Plated Steel Round Wound: 16.6 lbs
XL - Nickel Plated Steel Round Wound Steinberger: 14.8 lbs
XLS - Stainless Steel Round Wound: 15.5 lbs
Half Round - Stainless Steel Half Round: 17.1 lbs
Chromes - Stainless Steel Flat Wound: 17.6 lbs

Say you switch from XLS .009-.042s to Half Rounds .009-.042s - that's a variation of 1.6 lbs for just the E string, or more than 10% extra tension. That's significant enough to warrant a setup job.

Going between brands can lead to even more of a difference, both because of materials and windings, but also because string thickness for all but the first and sixth strings are likely going to vary.

No, it is high school science. A grade of B or better will help.

Keep calm , :lol:
I mean you don't need to adjust bridge or saddle height with new strings ; these adjustment are for action only .

With any string gauge , the bottom of the strings ( action ) will always at same height from the fret board with same neck curve

With new strings , yes action may change IF neck move but don't play with action adjustment .
Just adjust truss rod .
