Radial StageBug SB-4 Piezo Compact active DI Box for piezo pickups

48v Phantom Powered with Included Low Cut Filter


The Radial StageBug SB-4 is a ultra compact Active DI box, designed specifically for electro-acoustic instruments with Piezo pickups like guitar & violin

The SB4 is ultra compact, meaning that you can keep it with all your accessories in your instrument bag. It simply plugs into your instrument providing the link to your mixer and converting to a line level with the active circuitry allowing you to have longer lengths of cable without sound degredation. There's also a high pass filter to tame the bottom end and a polarity reverse switch to negotiate faze problems.

As with all Radial DI's the StageBug is built to withstand the rigours of a life on the road. A 14-gauge steel frame with a book-end design perfectly protects the precious components and connections for a long and healthy life.


  • Active DI optimized for piezo transducers
  • Smoothes out peaks, eliminates squawk
  • High pass filter eliminates resonance
  • Ultra compact to fit in your guitar case
