I want to add that the truer that your string rings, the better it intonates up and down the neck, meaning each note rings nice and clear just like all the rest. You can see how true your string rings with a tuning meter - just watch how much the needle bounces around at ever different note. The truer the ring, the less the needle bounces around. So technically a thru-neck would be the easiest to tune and the meter would settle on each note quickest. Alternatively an acoustic bass, especially if its X braced, does not have a very true ring tone in comparison. If your strings don't ring true, there are more conflicting frequencies (overtones) which are the cause all these other problems. In a subtle way the conflicting frequencies (noise) is less pleasant to listen to, and also has a minor affect on the singers ability to find right note. Another rather subtle effect is that you and your hands have to work harder if the strings don't ring true. Congrats to anyone in this thread who said they find their thru-neck bass resonates better or has longer sustain.
