It helps allow you to adjust the neck into a back-bow or an up-bow, depending upon what is needed for the instrument's set-up.

Two-way truss rods are a modern approach and are becoming common in instruments today. They help in instrument set-up, but there are instances where the adjustment range is inadequate. A one-way truss rod will simply counteract string tension and pull the neck into a 'back-bow.' This rod is found in most traditional and vintage instrument designs, and many modern instruments as well. The two primary categories of truss rods are one way and two way adjustable. Truss rods come in various designs and shapes are better suited for a particular instrument than others. This will give you the greatest possible control over the neck, which is important for instrument set-up and counteracting changes in temperature or humidity. It's highly recommended to use an adjustable truss rod. Many vintage instruments didn't use neck reinforcement, but suffer from the consequences-warped or twisted necks, poor playing action, and no simple method for adjusting or fixing the problem. Most modern fretted instruments have some type of neck reinforcement or adjustable truss rod. Make notes on the various aspects of the instrument's construction and get the necessary information from your notes. If you're uncertain whether flatsawn or quartersawn is best for you, we recommend playing several instruments of the style you are looking to construct. Flatsawn necks generally flex more than quartersawn necks, but in some cases a quartersawn neck can be too stiff. The neck wood can be flatsawn or quartersawn, depending upon the dimension of the neck stock, the intended neck construction technique, instrument style, tradition, and personal preferences. Most instrument necks are made of mahogany or maple. This information sheet reviews many of the methods of neck construction and neck woods. The types of woods and methods of neck construction affect the instrument's tone and durability, as well as the neck's stiffness, mass, and shape.

A familiarity with all types of instrument construction will allow you to determine what is most suitable for your needs or building techniques.
