Details

A smaller 4mm (5/32") Allen nut for most instruments. Smooth two-way action corrects upbow and backbow, giving complete control over the neck.

Easy to install. The Hot Rod® fits in a straight channel. For proper operation, this truss rod must be installed so that the active rod (the rod with the adjustment nut) is below the passive rod. A wooden filler stick is not required.

Smooth 2-way action with superior strength for stubborn necks.
Our Hot Rod neck adjustment system features twin rods in threaded brass collars. The stainless steel active rod turns for smooth neck alignment, with 2-way action to correct upbow and backbow.

The Hot Rod requires an access cavity for the adjustment nut, and a straight 7/32"-wide x 7/16"-deep slot (measured from the bottom of the fretboard) for installation.

Simply perfect

Installs easily and precisely and the fact that works in both directions allows you to straighten the fretboard wile leveling the frets. Perfect

Great Product!

I have purchased many of these truss rods and they work great. I use some woods harder then rock maple and have never had a problem with installation or use. Their service is top notch and I always get my order in two days. The trade secrets articles have given me the confidence and knowledge to do many guitar projects right the first time.
