Congratulations, you’re in a modern band. In addition to the basic vox, guitar, drums, bass, you’ve got yourself a keyboard player. Or maybe you’re using a laptop. Or maybe you’ve got a sampler or an iPod, or anything else that lacks the standard 3-pin XLR output. You’ve probably heard about a DI or a Direct Box, and how it might make these devices sound better or perform better during a live performance.
So, do you need one?
