The G0574 is the G1140 Edge Sander with the G0577 Radiusing Attachment included to produce the Guitar Fretboard Radiusing Sander.
Almost all guitar fretboards have a radius on them. For example, steel-string guitars generally have a 12", 14" or 16" radius across the fretboard. Electric guitars range from 10" to a compound radius that starts with a 10" at the nut and ends with a 14" radius at the pickup end.
