String Spacing Rule.
Get accurate spacing without calipers, calculators or
shop rulers. Our laser-etched stainless steel String Spacing Rule
quickly finds the right spacing for just about any stringed instrument.
It does all the math for you: proportional slot spacing automatically
compensates for string diameters, from treble to bass, so the thicker
strings won't seem crowded to the player.
The problem is: if you space the strings equally, they don't feel
equally spaced. The thicker bass strings seem crowded together. Each
gap between strings has to be slightly different to feel right to the
player. How do you calculate this? The String Spacing Rule takes care of
it, for guitars, basses, mandolins, and banjos.
String Spacing Rule is slotted so you can quickly mark the string
positions onto the nut. Use a scribe instead of a pencil, and it creates
extremely accurate starter grooves for your nut slotting files.
Easy to use.
Mark the two outer string positions onto the nut. Slide the rule over
the nut to find a set of slots that matches your two marks. Now just
scribe or pencil the string positions onto the nut! No measuring,
dividing or calculating — the rule does the math for you.
The rule's slots are laser-cut in a continuous scale
that wraps around both edges of the rule (our thanks to luthier Kevin
Ryan for creating this tool). Proportional slot spacing subtly
compensates for the diameters of the individual strings, from treble to
bass, to give the right feel and playability.
Not just for nut slotting.
You can use the String Spacing Rule to
notch Tune-o-matic bridge saddles, to lay out bridge pin holes, and
when notching archtop guitar, banjo, mandolin and violin bridges.
The String Spacing Rule is made of laser-etched flexible stainless steel that conforms to flat or arched surfaces.
