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
Ibanez RG a neck that is very thin in cross-section a wide, flatter than most (430mm/16.9in or 400mm/15.75in radius) double octave (24 fret) fretboard. Flatter radius on fretboards facilitate wider bends and lower string action at the expense of comfort in playing chords. For the virtuosic "shred" style of guitar playing or fast, aggressive thrash/speed metal rhythm, this type of neck is often preferred. The fretboards are usually made of maple or rosewood. The body of the RG Series features sleek, offset pointed double cutaways giving better access to the upper frets. Typically the body is made of Basswood or Mahogany, with
