Kustom KXB Series amplifiers are focused on producing great tone, rugged reliability and intuitive tone-shaping tools in one package. The Kustom KXB100 is a 100-watt bass combo amplifier with a 15-inch Kustom speaker and Bass, Lo-Mid, Hi-Mid and Treble controls. The preamp provides both Gain and Volume controls and is perfect for classic bass tones or more aggressive sounds with a hotter gain structure. Like every KXB amplifier, the KXB100 offers an auxiliary input for plugging in an MP3 or CD player to practice along with tunes and a 1/8-inch headphone input that silences the internal speaker for late-night playing. For performance flexibility, the KXB100 provides a balanced XLR Line Out with Ground Lift and Volume control. An Effects Loop with Send and Return jacks offers flexibility for integrating external effects and processors. All KXB Series amplifiers provide a three-year, transferable electronics warranty to give buyers extra piece of mind with their purchase.
