Guitar Frets are laid out to accomplish an equal tempered division of the octave. Each set of twelve frets represents an octave. The twelfth fret divides the scale length exactly into two halves, and the 24th fret position divides one of those halves in half again. The ratio of the spacing of two consecutive frets is formula_1 (twelfth root of two). In practice, luthiers determine fret positions using the constant 17.817—an approximation to 1/(1-1/formula_1). If the nth fret is a distance x from the bridge, then the distance from the (n+1)th fret to the bridge is x-(x/17.817). Frets are available in
Yamaha electric guitar models Only the RBX550 and RBX600 came with an optional maple fingerboard with black dot position markers (RBX550M, RBX600M). The RBX range has been updated in 1998 with a new body style, a 3D headstock with 2+2 (4-string) or 3+2 (5-string) tuner arrangement and a two-octave rosewood fretboard. The RBX6JM and RBX-JM2 6-strings topped the line, endorsed by Dream Theater bassist John Myung, the latter using a single custom-wound Seymour Duncan SMB-6A humbucking pickup, black hardware, an active 3-band EQ and a 24-fret rosewood fingerboard with oval abalone dot position markers.
