Radial StageBug SB-1 1-Channel Active DI-Box
The Radial StageBug SB-1 DI Box is meant for stage instruments that use long cables, including acoustic guitar, bass and even keyboards.
It has a compact and lightweight profile that is easy to carry around, and since it runs on 48V phantom power, you don't need to worry about batteries or wall warts.
At the core of his DI Box is an active circuit that converts your signal from high to low impedance, it also balances and buffers the signal to drive long cables straight to PA.
Other features include a 15dB pad for working with hot signals and a polarity switch that helps stop and prevent feedback.

The Radial StageBug SB-1 has a good reputation among musicians, specifically among bassists, guitarists and keyboardists. Bassists commend it's good low frequency reproduction, while keyboardists and guitarists are impressed with its clarity. Having been made by Radial, it is also applauded for its solid build and reliability.
There were a few who found the XLR port to be too stiff when brand new, but it did work well after a while. The side mounted controls can also be annoying to reach, but since it is mostly a one-time-setup gear, you won't have to deal with it regularly.
Overall, the Radial StageBug SB-1's simplicity and reliability is a good tool to have. Even more so when you consider its quality and accessible price tag.
