Output jacks are the only electrical part on a guitar that rely on a mechanical connection, making their design and build quality critically important. They must maintain a firm grip and keep delivering uninterrupted sound even when we bump the guitar plug, step on the cable, or get ourselves wrapped around a mic stand. And we need them to withstand these daily rigors for years without fail. That’s why DiMarzio only offers Switchcraft® jacks to our customers, the best built, truest-sounding, time-tested jacks on the market. We use them in our personal guitars and the shop instruments, because their sound is right and the grip is tight … enough said.
