I like the tuners smooth operation and perfect fit. The fast delivery was nice also. Will definitely try your other products. They also look great.

The experience and the ability to customize your thing is Awesome but the fit on the products not so much. The Locking key I received didnt line properly. I have to te drill holes in my headstock to Make then fit

Works as described. Good quality. Takes a while to get your order. Ships from China.

Everything was according to what was expected.

They delivered on time without any issues.
The products are very good quality and at a good price

Delivery is slow, but got here. 8n the end. The bass tuners look great, very well finished and looks good quality. Once fitted, they feel very notchy and sticky. The don't turn smoothly. Nowhere near as smooth as the unbranded tuners I took off, so certainly not an upgrade. I think I'll need to replace them with gotoh g7s.

I loved the product, the service from Guyker was first rate. Their communication is superb as well.

The quality of my new tremolo is fantastic. I will be buying more Guyker products in the future.

Ordered parts, no longer needed them, refused the package at the door, ask for money back since that is what they offer. Now I have no parts and no money. THIS COMPANY IS PURE SCAM!!

I am on my 8th high E string since installing the LP/ SG trem unit.. There was a burr that kept cutting the winding. The ball comes off or it breaks ALWAYS at the ball. I used a Dremel and sandpaper to dress the tailpiece, worked for a while then same problem. I then modified a nylon 1/8" nut to house the ball in. Hasn't broke since but looks like hell. Now it has started on the B string. It is a quality looking unit but they do an absolutely piss poor job of deburring and cleaning up the machining. I bought it for a 77 LP Std and am glad I put it in a POS $40. Silvertone SG for a test. Stay away from this. I thought of ordering some locking tuners from Guyker but their quality is non-existent. Dusenburg makes one for the same price

it was very uncomfortable proportional one side was way larger on the neck pick up ring and sanding it took forever u need to get your specs down more I bought a second pair just to see if it's a fluke I expect some sanding but not not that much

I placed an order but then noticed that they had entered the address wrong. When I message them to fix it, they refused and would not cancel the order or return my money. Now I am stuck with a ten day investigation through CashApp just to get my money back. Since then, I have been reading the reviews, how they mess up addresses, send empty boxes and do everything they can to not deliver the products. This company is an online fraud scheme running from China.

My order still not delivered yet,I’ve placed order on 10th April and still somewhere mocking around my parcel what’s going on?

Read carefully...Guyker it's a SCAM !!!

The facts:
In early January 2026, we purchased a $1,600 batch of hardware to prototype electric basses, they told us it would be shipped on January 22nd via YunExpress (the worst Chinese courier, check out the online reviews).
The package was lost.
Very late with the delivery of the basses to our customers, on April 1st, we paid $360 to have the goods reshipped via FedEx, but actually the goods were reshipped via YunExpress, which lost the package again.
When we realized they hadn't shipped via FedEx, we asked for an explanation, and they refunded us for a service they never provided.

In the meantime, we had to purchase the goods on AliExpress because the instruments had been designed with hardware supplied by Guyker.
We've currently spent over $2,000 on Guyker to make five musical instruments.
We've been forced to open a dispute on PayPal because the company is stalling and won't refund us for goods never delivered.

After four months, this is the situation.
As I wrote to Guyker, it's clearly a scam, because in theory they lost two batches of material, losing $3,200 plus they have to reimburse us for $1,600... so Guyker doesn't care about losing a customer like us (a company) and $4,800
I believe the system is simple: they pay influencers and customers (they asked me too) to advertise, collect the money from orders, create a fake shipment with an empty package with YunExpress, the goods are never delivered, and they refuse to refund.
Luckily, we insisted on paying with PayPal every time, taking on the fees rather than doing a bank transfer like they wanted... if we had done a bank transfer, we would have lost the opportunity to get a refund from PayPal.

I hope they're exposed by law enforcement and shut down as soon as possible!

The bridge was a direct fit. I was concerned about any alterations that needed to be done. No worries.

I run a guitar repair and electronics custom shop. My experience is limited to customer guitars with Guyker hardware that they installed. Guyker tuners, in particular, are among the worst I've experienced for quality. Tuner gears slipped, only to start turning again later in the rotation. I don't care what name is on tuners, whether they're locking or not, or how much you paid for the "upgrade". If Guyker quality goes up, I'll give them another chance. So far, what I see is poor quality and a massive marketing effort claiming to be experts in the field of guitar hardware. A lot of the hardware has a familiar look. It's obvious that this company sources parts from various factories that can slap the Guyker logo on them. It's up to Guyker to enforce some from of quality control. I'll be waiting in the wings, watching for quality improvements and watching the tuning woes of others.

I ordered electric guitar bridge, the quality was excellent and they notified customer when they shipped and delivered, I’m happy doing business with them. Keep it up!

First off I got three right side bass tuners and one left. I reached out and the guy said if I wanted left side tuners I would have to pay shipping…obviously didn’t read my email. I’ve reached out like 20 times and received no responses. So I’m reaching out here. Terrible customer service but what do you expect from a Chinese company with no customer service phone to contact them
This is the state of the service world these days.
Guyker is no exception. They just plain suck at taking care of customers.

Thanks everyone there i've been using your parts for a while now I usually get them from Amazon but now I can buy them from you I have you on my list good quality parts Thanks for being there I'll let everybody know
