Radial StageBug SB-1 Active DI Acoustic 48V Phantom Powered

Active Direct Box

The StageBug SB-1 is a compact active direct box designed to fit inside a guitar case for artists who prefer to travel light.


The Radial StageBug SB-1 is a super compact direct box that is designed primarily for acoustic guitars. As evident with the tests below, the compact size and streamlined feature set should in no way equate to lesser audio quality. The SB-1 delivers an exceptionally linear frequency response, virtually zero phase shift, and less than 0.005% distortion at all frequencies making the SB1 an ideal interface for all instruments.


  • Active direct box for acoustic guitar
  • Ultra compact to fit in your guitar case
  • Plug & play easy to use feature set
  • 48V phantom powered, no batteries needed!

Ultra-compact DI

The design begins with standard ¼ instrument input with a thru-put to feed your tuner or your on-stage amp. The ultra-quiet active circuit at once converts the signal from high to low impedance to reduce susceptibility to noise. The signal is then buffered and balanced for long cable runs to the PA system. 48 volt phantom provides the power, so the SB-1 does not require batteries or external supply to make it work. You simply plug in and you are ready to go!

StageBug SB-1 Applications

Acoustic guitar live

The StageBug SB-1 is plug & play easy to use. Connect and it automatically converts your Hi-z instrument signal to lo-Z and balances it for long runs.

Recording bass direct

Record your bass direct using the StageBug SB-1. This improves the tone and reduces noise by properly matching the impedance of the instrument.

Adding an amp or tuner

Use the SB1 thru output to feed your on-stage amplifier. For fun, add pedals after the SB-1 to color your tone on-stage while leaving the PA signal clean.
