## Description

The two-way adjustment design lets you turn each rod to adjust a guitar neck’s direction, helping with instrument setup and repair. This four-piece set includes matching 4mm L-wrenches for making adjustments at the rod’s hexagonal screw. It’s designed for use with guitars, basses, ukuleles, and other musical instruments. Need to work on more than one instrument? The rods offer a practical set of tools for luthier and repair tasks.

## Tips for day-to-day use
Before installation, confirm the rod length needed for the instrument’s neck. The listed length is 440 mm, and different types of guitars may require different adjustment rod lengths. Once you’ve selected a suitable rod, insert it into the neck’s hexagonal screw hole and use the wrench to turn it in the direction needed for the adjustment. This straightforward process makes the set useful for routine neck setup as well as repair work.

The rods can be used with electric and acoustic guitars, basses, folk guitars, ukuleles, and other musical instruments where the rod length and fit are appropriate. For a repair bench, having four rods and four wrenches on hand can support work across several instruments. For an individual repair, the included L-wrench provides the tool specified for turning the rod. Use the instrument’s neck and adjustment point as your guide when positioning the rod and making changes.

## Benefits
The two-way design supports adjustment in either direction, giving repair work a direct way to address neck alignment. Its intended use spans several instrument types, including electric and acoustic guitars, basses, and ukuleles, so the set can serve a range of setup tasks rather than a single guitar format. The 440 mm rod length and 4 mm wrench size also make it easier to identify the tool dimensions relevant to the repair at hand.

The metal-and-plastic construction is described as small and lightweight, making the rods easy to carry between a workbench and an instrument. With four rods and four L-wrenches in the package, the set suits repair work where several matching tools are useful. Compared with choosing a single adjustment rod for one repair, this multipack provides multiple rods for ongoing instrument maintenance or a group of compatible instruments.

## Before you decide
Which instruments can these rods be used with? They are intended for guitars, electric guitars, basses, folk guitars, acoustic guitars, ukuleles, and other musical instruments, provided the rod length and fit suit the instrument.

How do you make an adjustment? Insert the rod into the neck’s hexagonal screw hole, then turn it with the L-wrench to adjust the neck’s direction as needed.

What comes in the package? The package contains four guitar adjustment rods and four L-wrenches. The wrench diameter is 4 mm.

## Should you buy it?
Choose this set for instrument setup or repair when a 440 mm two-way adjustment rod matches the neck and you want multiple rods with corresponding L-wrenches on hand. Its use across several guitar types, bass, and ukulele makes it a practical fit for a repair bench or for maintaining compatible instruments at home.
