If you find yourself in need of a screwdriver when getting ready for a gig or a recording session, it's likely you really need one — and that's why you keep this Dunlop Screwdriver Set in your gig bag. Think about it: loose tuning machines, loose tremolo plate screws, and that infuriating pedal with a screwed-on battery compartment are just a few examples of things that could seriously hurt your gig or session if you don't sort them out quickly. With two Phillips-head bits and two flathead bits, the Dunlop Screwdriver Set works with practically every screw in your guitar or bass rig, and Sweetwater highly recommends keeping one in your equipment bag.
