Its passive design employs a high-performance Eclipse ET-DB3 transformer that delivers clear, warm tone while eliminating ground loop hum and interference. Ideal for bass, keyboards, and acoustic guitars, the SB-2 handles high signal levels without distortion and features a 1/4" input, 1/4" thru-put, and balanced XLR output. The ground lift switch helps resolve hum issues, and its heavy-duty steel chassis ensures durability on the road. Reliable and easy to use, the SB-2 is a trusted tool for musicians and audio professionals looking for clean signal transfer without the need for power.
