Balanced line driver for guitar and bass

Take your tone further
The SGI sends guitar signals across long distances without signal loss or noise, while retaining the original tone of the instrument. In the studio, it allows the guitarist to sit in the control room and connect to a distant guitar amp. On stage, the SGI can be used to play the guitar amp using off-stage isolation cabinets or it can be used to manage guitar signals to and from wireless systems, pedalboards and amplifiers. The SGI consists of two boxes: the SGI-TX transmitter and the SGI-RX receiver. The connection between the TX and RX is made using a standard balanced XLR microphone cable. To use, you simply plug your guitar into the SGI-TX input and connect your amp from the SGI-RX output and you are set to go. The SGI does all of the balancing, buffering and impedance matching for you.
