The SansAmp Bass DI is a bass preamp DI box that converts an unbalanced bass output signal into a balanced signal for use with mixing desks or recording equipment via an XLR output. It also functions as a hybrid combination of a bass preamp and an overdrive pedal, capable of producing a wide range of sounds from vintage tube tones to modern slap sounds and gnarly distortions.
