Kustom KXB Series amplifiers are focused on producing great tone, rugged reliability and intuitive tone-shaping tools. The Kustom KXB20 is a 20-watt bass combo amplifier with a 12-inch Kustom speaker and Bass, Lo-Mid, Hi-Mid and Treble controls. It provides the right amount of power and EQ to dial in classic, thumping bass tones as well as more aggressive, modern tones. Like every KXB amplifier, the KXB20 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 so you can be a good neighbor.
