What Is Guyker?
Guyker is a guitar hardware brand focused on replacement and upgrade parts for electric guitars, bass guitars, and custom instrument builds. According to the company, its story began in 2011 with a small team of musicians and tinkerers who wanted to create guitar parts that better matched their own needs.
Today, the Guyker catalog covers a surprisingly broad range of components including locking tuners, traditional tuning machines, guitar bridges, tremolo systems, tailpieces, control knobs, pickups, pickguards, electronics, neck plates, bridge accessories, and other hardware.
This makes Guyker particularly interesting for players who enjoy modifying instruments rather than simply buying a guitar and leaving every factory component untouched.

1. Guyker Locking Tuners — One of the Best Places to Start

If you are looking for a practical first upgrade, Guyker locking tuners are one of the most obvious places to start. Locking tuners clamp the string at the tuning post instead of relying entirely on multiple wraps around the post.
This can make restringing faster and can reduce the chance of string slippage when the guitar is properly set up.
- Faster string changes
- Reduced excess string wrapping
- Multiple gear ratios and layouts
- Chrome, black, gold, rainbow, and other finishes
- Options for different headstock configurations
Why Locking Tuners Are a Popular Guitar Upgrade
Standard tuning machines are perfectly usable when they are functioning properly, so locking tuners should not be viewed as a magical fix for every tuning problem. Nut friction, bridge setup, string installation, and playing technique can all affect tuning stability.
However, locking tuners can make string installation more consistent. Instead of winding several turns around the post, the string can be pulled through, locked in place, and brought to pitch with less excess winding.
Guyker offers several layouts, including 3R+3L sets commonly associated with many double-cut and single-cut guitars as well as 6-in-line designs for ST- and TL-style instruments. Because tuner dimensions are not universal, checking the mounting-hole diameter and screw arrangement before buying is essential.
2. Guyker Tune-O-Matic & Roller Bridges
Bridges are another major category in the Guyker catalog. Players working on LP-style, SG-style, Jazzmaster-style, Tele-style, Strat-style, and other instruments can find multiple bridge designs and replacement components.
Guyker’s Tune-O-Matic roller bridge options are particularly interesting for guitars that use tremolo systems or for players who want strings to move more freely across the bridge saddle.
- Tune-O-Matic bridge designs
- Roller saddles
- Multiple metal finishes
- Bridge accessories and replacement studs
- Parts for several popular guitar styles

3. Tremolo Systems and Bridge Hardware
For more involved guitar modification projects, Guyker also sells tremolo systems, bridge arms, blocks, fine-tuning screws, saddles, studs, and related bridge hardware.
This part of the catalog is better suited to players who already understand guitar setup or who have access to a guitar technician. A bridge or tremolo replacement involves more measurements than replacing a control knob, and seemingly small differences in post spacing, stud diameter, bridge radius, or string spacing can determine whether a component fits correctly.
Important Compatibility Tip
Do not buy a bridge simply because the product title mentions your general guitar style. Measure the existing bridge, mounting posts, string spacing, radius, and relevant screw dimensions first. Two guitars with a similar body shape can still use different hardware specifications.
4. Guyker Knobs & Cosmetic Hardware

Not every guitar upgrade needs to change how the instrument performs. Guyker also offers a large selection of cosmetic components that can completely change the appearance of a guitar without replacing the body or neck.
Control knobs, neck plates, pickup rings, strap buttons, tuning machine finishes, and other small pieces allow players to create a consistent visual theme across the instrument.
- Chrome and nickel finishes
- Black hardware
- Gold hardware
- Rainbow and colorful finishes
- Modern CNC-machined designs
How to Choose the Right Guyker Parts
The biggest mistake when buying replacement guitar hardware is assuming that parts are universal. Many guitar components look nearly identical in photos but use different measurements.
1. Measure First
Measure your existing part before ordering. Depending on the component, this may include post diameter, mounting-hole spacing, string spacing, screw position, shaft diameter, or bridge radius.
2. Match the Layout
For tuning machines, check whether your instrument uses 6-in-line, 3R+3L, or another configuration. Also compare the screw and locating-pin arrangement on the back of the headstock.
3. Check the Product Drawing
When a product page provides dimensional diagrams or measurements, compare those directly with your instrument instead of relying only on model names.
4. Consider Installation
Some parts are simple replacements, while others may require drilling, filing, soldering, setup work, or professional installation. Decide how much modification you are comfortable performing before ordering.

Who Should Buy Guyker Guitar Parts?
Guyker makes the most sense for guitarists who enjoy modifying instruments or want to replace specific pieces of existing hardware instead of buying an entirely new guitar.
Players upgrading an affordable guitar
An inexpensive or mid-range guitar can sometimes benefit from targeted upgrades. If the instrument already has a comfortable neck and a body you enjoy, replacing tuning machines, hardware, or controls can be more appealing than replacing the guitar itself.
DIY guitar builders
The wide range of finishes and hardware types makes Guyker particularly useful for custom builds where the appearance of every small component matters.
Players restoring older instruments
Replacement bridges, tuners, knobs, plates, and related hardware can also help when restoring a guitar with worn, damaged, or missing components.
