What to know before buying

Listing details to confirm

Confirm the tuner dimensions and mounting compatibility using the listing's parameter drawing before ordering. The title calls the set drop-locking, while the feature details describe open-gear tuners and do not clearly confirm a locking mechanism. The page also alternates between a sealed-lubrication claim and an open-gear description, so these construction details are inconsistent. The hardware is claimed in feature text, but the supplied package inventory is empty, so confirm it is included with the selected listing.

Who is it for?

A good fit for

Bass players replacing a complete four-string set with a 2R + 2L layout.
Owners of electric Jazz or Precision-style basses who can verify the mounting dimensions first.
Buyers seeking gold-finish open-gear tuning machines with a stated 1:22 ratio.

Less suited to

Players who need a confirmed locking tuner design without clarifying the listing's conflicting descriptions.
Buyers who cannot check the tuner dimensions against their instrument.

Frequently asked questions

Will these tuners fit my bass?

The listing identifies them for electric Jazz or Precision-style basses, but fit depends on the mounting dimensions. Compare your instrument with the parameter drawing before ordering.

Are these definitely locking tuners?

The title uses drop-locking wording, but the feature text describes open-gear tuning machines without clearly confirming a locking mechanism. Check with the seller if locking function is essential.

Is mounting hardware included?

Feature text says screws, bushings and washers are included, but no explicit package inventory was supplied. Confirm the selected listing's contents.
