GUYKER 7R Locking Tuning Machines Set 7 Right-Handed Machines in a Row Gear Ratio 1:18 Metal Chrome For 7-String Head Guitar
You already have the maximum available quantity in your cart.
The GUYKER locking tuning machines in the 7R version consist of a set of seven right-handed machines that are mounted side by side in a row on the head of the guitar. The gear ratio of 1:18 allows for fine tuning of the string, and the set tuning remains stable even during extended playing. The designation 7R indicates seven machines for the right side, which is the layout for a head with seven machines in a row. The body, peg, and control knob are made of metal with a shiny chrome finish in silver colour. This set serves as a replacement for worn machines or as an upgrade for a guitar with a 7-in-a-row head.
Each machine features a knurled lock wheel on the back, which securely holds the string in the peg. Thanks to the lock, fewer turns of the string around the peg are needed, string changes are quicker, and tuning stabilises faster after stretching. The peg has a diameter of 6 mm and the threaded part intended for the hole in the head has a diameter of 10 mm. The included housings with hex nuts, washers, and screws secure the machine in place and prevent it from rotating.

Before installation, remove the original machines and ensure that the holes in the guitar head match the threaded part with a diameter of 10 mm and that the spacing matches the original machines. Insert the machine into the hole, secure it from the back with a screw, and tighten the housing with a washer from the front. Thread the new string through the hole in the peg, tension it by hand, and lock it by turning the wheel on the back. Then fine-tune it with the control knob. The chrome surface can be wiped occasionally with a dry soft cloth to keep it shiny and free of fingerprints.
The GUYKER 7R locking machine set contains everything necessary for replacing tuning machines on a guitar with a head featuring seven machines in a row. The gear ratio of 1:18 ensures precise tuning, and the string lock simplifies string changes. The metal body with a chrome finish matches the silver hardware of the instrument. Mounting materials are included, so you can install the machines immediately after unpacking. The package includes 7 machines with the same appearance and gear ratio.
