Retrospec Juice Box Direct Box

The Juice Box uses a transformerless, all-tube design. By removing the transformer, it eliminates the coloration and signal degradation often associated with traditional DI boxes, resulting in a much wider frequency response and a cleaner, more transparent signal path.

Yes. The Juice Box features a balanced XLR output with variable gain, which provides enough signal strength to potentially bypass the need for an external preamp, making it an excellent choice for direct recording.

It is built for both. While it is a fantastic studio tool for bass and keyboards, its solid aluminum chassis is durable enough for the stage, and it excels at adding clarity and punch to acoustic instruments in a live mix.

No, it does not rely on phantom power. It features an internal linear power supply and connects to a standard AC outlet, which ensures consistent voltage and stability for the tube circuitry.

The high-impedance, tube-buffered input is specifically designed to prevent 'loading' your instrument's pickups. This preserves the natural frequency response of your bass or guitar, ensuring you get a full, present sound rather than a dull or thin signal.

The Juice Box includes an audio ground lift switch. If you encounter ground loop noise when connecting to your recording gear or PA system, simply toggle this switch to isolate the ground and eliminate the interference.
