DI Boxes For Sale on Reverb

It's not always feasible to have an amplifier for your acoustic-electric guitar, keyboards and synths, and sometimes the boomy sound of a mic'd up amp on stage or in the studio needs to be blended with the direct sound for clarity and definition.

Perhaps you're looking for a way to properly interface your laptop to professional gear—that's where a DI box comes in. Shop Reverb's selection of active and passive direct boxes, new and used, and get the natural sound of your instrument heard by the masses.

DI Box Definition

The DI in DI box stands for direct input or direction injection, and what a DI unit does is convert an unbalanced, high-impedance signal into a balanced, low-impedance signal, which allows players to plug an instrument directly into a preamp, mixer, or recorder at the right impedance for a cleaner, lower-noise sound.

DI boxes can be great tools for players trying to combat signal degradation/loss as a result of using long cables or passing through a lot of signal-sucking effects and pedals. For bassists, guitarists, and keyboardists alike, a DI box can be an invaluable tool.

To learn more about the various types of DI unit—active DIs, passive DIs, multichannel DIs, integrated DIs, reamp boxes, etc.—and for guidance in how to choose the best DI for you and your instrument, check out our DI Box Basics Guide.
