this is my first time intonating a guitar. my problem is that when i turn the saddle screws i get no change while reading the tuner.

any tips you guys could give me.
The way you've worded it makes it sound like you are plucking the string, then turning the screws, which probably won't register. You need to tune the open string, pluck the harmonic, turn the screw, then retune the open string and then measure the harmonic.

The only other thing I can think of is that you're perhaps turning the screws on the top of the saddle, not the one on the butt of the bridge.
might be a bad tuner

Where's Waldo?
