Oh yeah. Half a turn on a tuning machine means a lot but on an intonation screw it's close to nothing. Think about it like it's a fret. Sure the frets get smaller as you go higher, but if there were frets all the way down to the bridge, they would be about 7mm between the last frets. If you are a half step out, you need to move the saddle, about half of that 7mm. A half turn on the saddle screw is only about a quarter of a mm.kitekrazy said:.......I spent a little more time setting the intonation. I guess it takes more than half a turn to make a difference. Plus I made sure I wasn't bending the strings when I adjusted.
