Fret necessary?
Instruments- discuss specific features, luthiers, instrument problems & questions
Randy makes a good point. Diatonic frets create bumps just as much as chromatic frets do, and decent noter players seem to adjust just fine.
When you slide with a finger--which flatpickers and chorders do all the time--those bumps also exist. But what's cool about the technique is that our ears play a trick on us. Instead of hearing each of the notes that correspond to each fret, our ears hear those slides as genuine slides, filling in all the microtones as thought there were no frets at all. That is why a hammer-on sounds so different than a slide. For example, when you slide from 3 to 4 and when you hammer on from three to four, you are just playing two notes. But when you slide, our ears hear an infinite number of tones in between those two. (Having said all this, one can slide in a precise and deliberate manner to approximate the sound of a hammer-on or pull-off, but now we're getting into nerdy nuances.)
As a flatpicking and chording player, I use extra frets all the time and wouldn't want it any other way. But I understand the history of the instrument and respect deeply those who play truly diatonic instruments in the traditional ways. That alone is a reason not to add extra frets. The argument about "bumps" is less convincing to me, for I think you can adjust when you want to slide over the frets you don't need in a particular passage.
