in every area even today. Digital tuning being convenient? maybe, inexpensive? definitely not.
When it comes to "效果" there are so much more things that can make a difference in a tuner than merely digital-vs-analog tuning technology, even the visual effect of a tuning dial and a lighted scale could make differences. I wouldn't jump to a conclusion that quickly and say it's digital-analog that's making all the differences in "效果".
Besides, I chose not to discuss what "效果" exactly is, because that's very subjective.
