I've been having trouble getting my strings properly intonated, and it seems like it's because the saddles are getting stuck. What it looks like is that they're pressed against each other so tightly that it's causing resistance. It's bad enough that I accidentally stripped the screw for the G-string saddle while trying to move it closer to the bridge.
Is this normal? If not, what can I do about it? It's a Squier guitar, so I'm wondering if it's just because its a cheaper tremolo assembly. In that case, I could easy solve my problem by upgrading the part.
