By changing the shape of the saddle so the different strings have different effective lengths, as needed. Or by changing strings till you find some that intonate better. It's really impractical to adjust intonation on most acoustics. Accept that it's in the ballpark and play on.

Great!

I figure, though, that an acoustic's unlikely to ever be perfectly intonated on all strings.

Just curious, how did you move the saddle?

Here's a question - given the intonation issues that are part and parcel with an acoustic, why don't more acoustic guitars use some form of adjustable bridge? Is it simply due to construction issues? Asthetics? I would think that some kind of wooden bridge plate with adjustable metal/graphite saddles would allow for better setup for an acoustic...?

I suspect it's mainly a matter of "This is how it's always been done."

Guitarists are about the most conservative group of people I know...

It's more complicated than that.

Adjustable bridges mean adjustable distribution of mass, and changing the way mass is distrubuted on the top of an acoustic changes the way the top vibrates. The top of the guitar is where almost all of the volume comes from in an acoustic.

When a luthier builds an acoustic guitar, they keep shaving off tiny bits from the top braces (the process is called "top tuning") until they get the best possible balance of frequencies. If you have an adjustable bridge, your're not just changing the intonation - you're also changing the top tuning. It's pretty sensitive, and you might end up with perfect intonation, but some dead frequencies.

Which is exactly why I stick with electrics!
