Radial Engineering StageBug SB-1

The Radial StageBug SB-1 is a high-performance active direct box made for players that are on the move. Made to fit inside a guitar case, the SB-1 is the smallest Radial DI box ever! But don’t let the small size mislead you—this ultra-compact StageBug sounds absolutely terrific.

Keeping the design simple, it has a standard 1/4" 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 sent out the balanced XLR output for long cable runs to the PA system. It uses 48V phantom to provide 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.
