Independent shopping perspective
The Korena take
StageBug SB-2 routes a 1/4-inch instrument signal to an onstage amp through its thru output while sending a balanced XLR feed onward. Its Eclipse ET-DB3 transformer handles impedance matching and signal balancing, with isolation plus a ground lift to address ground-loop noise. For active basses and digital pianos with higher output, engage the -15 dB pad. The stereo-to-mono merge also lets stereo keyboards or computers feed one PA channel without changing the source to mono.
Strong match
Who this is for
- Sending an instrument to both an onstage amp and a balanced XLR destination.
- Combining a stereo keyboard or computer feed into one PA input channel.
- Using active basses or digital pianos whose output can overload the input.

Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can the SB-2 feed an amp and the PA at once?
Yes. Its 1/4-inch input and thru output can feed the onstage amp while its XLR output provides the balanced signal.
02Can I connect a stereo keyboard without switching it to mono?
Yes. The stereo-to-mono merge function combines stereo keyboards and computers without changing the source setting.
03What addresses ground-loop noise?
The transformer isolates input from output, and the SB-2 also has a ground-lift switch.
