The 4-Play is a DI box specifically designed for multi-instrumentalists, providing the ability to quickly and silently change instruments on stage. With four balanced outputs, each instrument has its own channel in the PA and monitors.

Many performing multi-instrumentalists will have each of their instruments feed a separate channel in the PA system, allowing for individual level, EQ, and effects settings. Typically this would require multiple DI boxes and instrument cables, creating a mess on stage that can be difficult to manage. With the 4-Play, you only need to connect one cable to the input of the pedal, and it provides you with four DI outputs to feed the PA system. Not only does this mean fewer cables on stage and less devices to keep track of, but it also eliminates the need to flag down the sound engineer when you need to switch instruments during a performance. The 4-Play puts you in control, while streamlining your setup on stage.
