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.
