Intonation…fretless vs fretted

Same here. I have 11 electric basses, two acoustic electric basses and two uprights. All that have adjustments for intonation (11) don’t ever get out of intonation unless I play the strings into the ground & even then the intonation doesn’t get far off, it just gets hard to check because the strings are hard to get precisely in tune. I don’t play strings that long like I did when I was young and broke.

 

This is only true for people that are not capable of hearing if a note is out of tune or not.
