The banjo is actually a good example- if you rely on a tuner for the open strings you will find that the second string (b) is out with other strings further up the neck, so conventional wisdom is that you tune it relatively instead. I tend to tune it at the eighth fret to the open 5th string (high g), so at least all the g notes chime in tune. By the way, banjos don’t burn very well because of all the metalwork - some have famously survived house fires (probably to the disappointment of the arsonist neighbour).
