Actually I use 12th fret harmonics all the time, both for guitar and bass, on all strings more or less.
Here's the thing: when bands arrive in the studio, I take care of the intonation of their instruments (which is never accurate). Then we have the next problem. People don't know how to use a tuner. It's unbelievable and it always pisses me off so much. And you have the people who pluck the strings like "beeeeoooooooouuuuuwwwwwwwww beeeeeooooooouuuuuwwwwww" and trying to tune at the same time. Playing low tuning with a 009 set most of the time. This, mixed with the other guitar player in the band who tunes by lightly blowing some air on the string or something...
Then, of course, you also have the people who change the strings 2 minutes before it's time for their take, on a guitar with a Floyd Rose. And they go over the strings time after time after time and have NO idea about tension and how you can try to get the tuning done a faster way.
So in the end, I always grab the guitar and do the tuning for them.
What does this have to do with this thread? Well, the lower the string, the more "beeeeooooooouuuuwwww" you will have going on. So in some cases it might just be needed to pluck the string softer. Although if the bass is good intonated, a 12th fret harmonic will be the best option in my opinion.
