Radial Stagebug SB-1 active 48v Phantom DI - Used

The Radial StageBug SB-1 is an ultra-compact active direct box designed for acoustic guitars, passive basses, and other instruments with high-impedance outputs. Its active circuitry converts the instrument signal to a balanced, low-impedance output, making it suitable for long cable runs to a mixing console, PA system, or recording interface. It operates entirely from 48V phantom power, eliminating the need for batteries or an external power supply.

Condition:

This DI is used and remains in very good overall condition. It shows light cosmetic wear consistent with normal use, including minor marks on the enclosure. The connectors, switches, and controls are clean and well kept. Please refer to the photos for a detailed look at the cosmetic condition
