Potential Saving: 10%

How I Build My Guyker Upgrade

Before focusing on the discount, I decide which parts of my instrument I actually want to upgrade. Guyker offers hardware across categories such as locking tuners, bridges, tailpieces, knobs, pickups, pickguards, and electronics.

I compare compatible options first and add the parts that suit my guitar or bass to the cart.

Applying [LSTNUP] at Checkout

After preparing my order, I proceed to checkout and enter [LSTNUP] in the available discount code field.

If the selected Guyker products meet the applicable conditions, the order total may receive a 10% discount. I review the updated amount before completing payment to make sure the discount has been applied.

Comparing My Order Total

I prefer to evaluate the discount by comparing the checkout totals directly.

I check the original cart value, apply [LSTNUP], and then review the revised amount. This is particularly useful when purchasing several upgrades together, such as tuning machines, a bridge, and matching knobs.

Choosing Parts Before the Discount

The discount can improve the overall value of my order, but compatibility and the type of upgrade remain more important. I consider the instrument design, hardware dimensions, finish, tuning requirements, and the purpose of each replacement part.

Once I have selected the right components, I use the available discount to see whether I can reduce the final cost.

My Final Guyker Checkout Review

Before placing the order, I check my selected guitar or bass hardware once more and confirm that [LSTNUP] has been entered correctly.

If the eligible Guyker products qualify, the 10% discount should be reflected in the checkout total. I use this final amount to evaluate the complete cost of my instrument upgrade before completing the purchase.
