Testimonials

“I really appreciate the extra mile you guys are going to make sure your customers are satisfied. I have a degree in business and I've studied all that stuff about how companies are doing their best to keep their customer satisfied through marketing and incentives, but I can't think of another company (in any field) that makes me as satisfied as you guys do. I'm sure there are some places that sell materials here in Japan, but even with extra cost of shipping and customs fee, I prefer to buy from LMI, because I can trust LMI's service and quality of materials. No marketing and incentives can match the solid good service and I'm a very happy LMI customer.”

Truss Rod, double action welded nut

Rod2wayDblAction

Longer keystock facilitates easy nut adjustment.
MadeintheUSA125

Protected by U.S. Patent No. 6,259,008, this is the best rod on the market these days. Combining the best of several designs, this rod offers adjustment capabilities as well as several other advantages over rods of similar design. This rod requires a 3/8" deep x 1/4" wide slot. As the square stock bears against the bottom of the fingerboard, no filler strip is necessary as described with the TRST-style rod. Turn the nut one way and the rod turns one way, turn the nut the other way, the rod turns the other way! With this rod the nut is actually welded onto the adjusting rod which has been right-hand threaded on one end, and reverse threaded the other. The bottom, round rod is covered with heat-shrink tubing like our compression rod, to protect against rod buzz. This rod is essentially installed just like the TRST rod, but you need to rout a slot 1/4" wide x 3/8" deep. The bar-stock dimensions and the round-stock OD with the heat-shrink tubing is the same and makes for easy installation. This rod goes with all of pre-carved necks (see neck woods).

Please Note: With the exception of the TRMRmade in Japan, all of the truss rods we carry are made, inspected and tested in the USA. Still, we urge you to carefully inspect each rod you receive to make sure it meets your specifications. Once installed, a truss rod can be extremely difficult to replace or repair. Put each rod in a vice and turn the nut beyond its normal range of adjustment (turn it both ways if it is a two-way rod). As with all of our products, LMI is not responsible for any effect of a defective truss rod, or any related costs, beyond the price of the truss rod itself. In keeping with our return policy, we are happy to replace or refund the cost of any rod that you are not happy with. Please call for a return authorization number within 2 weeks of receiving your order. Modification of the rod in any way voids your warranty.
