- Sometime ago I entered a small music store and noticed an
- electric guitar whose fingerboard frets gradually became
- slanted as you approached the heel (body end) of the neck
- (that is the frets progressively tilted away from the
- perpendicular).
-
- I have seen photopgraphs of Rickenbacker guitars with slanted
- frets, but the fret angle appeared to be constant (vs.
- a progressive slant on the instrument I saw in person).
- I have also read a handful of books on guitar building and
- never enountered any mention of such a design.
-
- Has anyone enountered anything similar or understand the
- principle involved ?
-
- The theory is that the scale length of an instrument makes a contribution
- to the sound; guitars with longer scales (Fender's are typically 25.5
- inches) have a brighter sound than guitars with shorter scales (Gibsons are
- typically 24.75 inches), all else being equal, and that a shorter scale
- might be preferable for the higher strings and a longer scale might be
- preferable for the lower strings. Y'know, like in a piano, harp, autoharp,
- harpsichord, or clavinet.
-
- (I don't mean to imply that this is the only reason, or even the most
- significant reason, Fenders typically sound brighter than Gibsons. If you
- want to experiment with smaller scale lengths, simply capo up a fret or two
- and tune down so that the capo'd open strings are at the standard tuning.)
-
- I've never played one of these guitars, so I can't tell you if the effect
- is noticable or not.

- It sounds like someone built a guitar with a graduated scale length. (It
- also sounds like some luthier got really loaded :-) I can imagine the
- headache of doing this, since the equation governing fret placement is
- an exponential one, there couldn't be too many solutions to 6 different
- scale lengths where the fret position on each string allows frets to be
- placed this way as opposed to 6 fret-lets per half tone (giving 132
- frets on a normal 22 fret length fingerboard ) I guess there'd be a bit
- more slop in intontation than we're accustomed to on normal
- fingerboards.
-
- Um, you need to work on your math -- while the fret placement is in fact
- exponential, all the distances scale linearly, so neither fretlets nor
- curved frets are necessary. (Curved frets would look pretty cool, eh?)
