Guyker review 2026

Guyker is a good fit for players and hobby builders who want budget-friendly tuners, bridges and small hardware with clearly listed specs. Skip it if you need a part tomorrow, since standard delivery is quoted at 7 to 14 business days after 1 to 3 days of processing. Measure your peg holes, string spacing and post spacing before ordering, because fit is the whole game with replacement hardware.

About Guyker

Guyker sells replacement hardware for electric guitars, basses and acoustic guitars: tuning machines, locking tuners, tremolo and Tune-O-Matic bridges, control knobs, pickup covers, nuts, saddles and the small screws that hold everything together. Its about page says the brand started in 2011 with a small team of musicians and tinkerers, and it describes itself as selling to players in more than 60 countries.

Catalog and prices

The catalog holds about 920 products, with a median price of $19.99 and a range from under $1 to about $367. The biggest groups are knobs, bass bridges, locking tuners, tuning machines and tremolo bridges. Small parts are cheap: the CKB041 Acrylic Candy Stripe Control Knobs and the LZ004 Stop Tailpiece Studs and Bushings set each list at $4.99. Mid-range upgrades include the GK102SP-A Locking Guitar Tuners at $49.99 and the GG903X 6-Point Tremolo Bridge at $49.99. At the top, the GG901S Fine-Tuning Tremolo Bridge for headless and standard guitars lists at $179.99, and the GKS100-400 Double-Locking Tremolo System at $159.99.

Bass players get more attention here than at many parts shops. There are 8-string bass bridges, sealed and open-frame bass tuners, and the GK-530T Carbon Fiber Tuning Pegs at $104.99 with a 1:28 gear ratio.

What sets it apart

The product pages are spec-heavy in a useful way. Listings call out gear ratios, string spacing in millimeters, peg hole sizes and shaft fit, which is what you actually need to know to avoid a part that doesn't fit. Many tuners come in bright Dopamine color finishes, so Guyker also works for cosmetic mods. Items tagged Ready to Ship (US) are worth noting if you are in the States. About 177 products were on sale when the data was collected, with some steep markdowns, such as the BB101 Locking Bass Tuners at $79.99 against a $160.99 compare-at price.

Shipping, returns and warranty

Standard shipping is free on orders of $59.99 or more and $5.99 below that, with 1 to 3 business days of processing and 7 to 14 business days of transit for the main shipping zone (US, Canada, Australia and much of Europe). Customs duties are the buyer's responsibility, and the store doesn't ship to P.O. boxes or APO/FPO addresses.

You can return items within 30 days of purchase in original condition with packaging intact, but you pay return shipping if the reason is personal, like ordering the wrong size. Defects need to be reported within 48 hours of delivery, and Guyker covers shipping on approved replacements. A separate one-year limited warranty covers defects in workmanship or materials for the original buyer, though shipping costs on warranty claims fall on you.

What stands out

  • Spec-first listings. Gear ratios, string spacing, post spacing and shaft sizes are spelled out on product pages.
  • Deep bass section. Bass tuners, 8-string bridges and bone nuts for 6-string basses, not just guitar parts.
  • One-year limited warranty on Guyker parts bought from its own site.
  • Ready to Ship (US) tags mark items stocked for US delivery.
