I realize that not everything you read on the internet is true so I'm trying to separate fact from fiction here. I have encountered a statement multiple times that contradicts something that I'm seeing with my own two eyes and it is this.. "You can't swap out that neck with that other neck because they have a different number of frets." As I'm typing this, I am looking at my formerly 21 fret bass which now sports a 20 fret neck. It intonates perfectly and I have not had a single issue. Am I missing something here? As long as you have sufficient travel in the bridge (mine is almost maxed out now on the A string), is there any reason that you would advise someone not to do this? If there is a reason that I'm totally not getting, please clarify.
