Guitar techs and DIY modders, here's a handy bulk pack: 50 sets of imperial-sized humbucker pickup height adjustment screws and springs. These are the standard screws and little springs that go under your humbucker pickup to let you raise or lower it. They fit most common humbuckers from brands like Seymour Duncan, Dimarzio, Gibson, and many others. Brand is unbranded/generic, but they're the correct size and thread. Perfect for when you're installing new pickups that didn't come with hardware, or if you've lost some screws during a setup. Having a bunch of these on hand is super useful for any guitar workshop. Makes fine-tuning your pickup height for perfect tone and output a breeze. A cheap essential for any guitarist's parts drawer.
