Truss Rod

Single Acting: Allows for adjustment of the neck in order to correct for too much relief in the neck due to variables, such as temperature and humidity changes. This style of truss rod is common with vintage (and some modern style) necks. One of its advantages is that it is slightly lighter in weight than a dual acting rod. From our experience, there is no significant sonic advantage when compared to a dual rod. Additionally, you can only correct for too much relief in the neck. This rod cannot correct a back bow situation. However, we do take back bow into consideration when installing and setting the neck up for fretting. For the vintage enthusiast who seeks the vintage vibe, this rod is an excellent choice. Our single acting rods come with the standard cross-slotted or Phillips-style truss adjustment nut. Single acting rods are available as a heel adjustment only.

Dual Acting: Allows for adjustment of the neck to correct for BOTH back bow or under bow (relief). Most modern constructed necks have this type of rod. It is the preferred truss rod here at Musikraft due to its versatility. This rod is available as a heel or a headstock-adjusting rod and has a female allen head receptacle as its adjustment nut. 

Vintage Dual Acting: We are happy to introduce a new truss rod option here at Musikraft. We wanted a way to offer both the vintage look as well as the reliability of a more modern functioning truss rod. Single acting truss rods with a double slotted adjustment nut are typical with vintage Fender style neck construction. The down side to this method, is the fact that you can only correct for seasonal changes if the neck has too much relief  (up-bow). But what do you do if your neck does not have any relief or is back bowed? A neck with a dual acting rod provides the ability to correct for both up-bow and back-bow. With a single acting rod you are limited to correcting for up-bow only. We found that a lot of our clients are willing to risk not being able to correct for back-bow in order to maintain that vintage look and vibe.  Now you can have the best of both worlds: a vintage style truss rod that works like a modern dual acting rod.  Our new vintage dual rod looks vintage but acts modern. Our vintage dual rod adds 2 ounces of mass to the neck. More mass equals more tone and sustain - not to mention the dual function adds piece of mind.
