Kustom KB series amplifiers are focused on delivering great tone, rugged reliability, and intuitive tone-shaping tools. The Kustom KB100 is a 100-watt bass combo amplifier with a 15" Kustom speaker and Bass, lo-mid, hi-mid and treble controls. The combo amp's preamp provides both gain and volume controls and can dial up classic bass tones or more aggressive sounds with a hotter gain structure. Like every KB amplifier, the Kustom KB100 bass amp offers an auxiliary input for plugging in an MP3 or CD player to practice along with tunes and a 1/8" headphone input that silences the internal speaker for late-night playing. For performance flexibility, the KB100 bass combo 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. The Kustom KB bass amplifier provides a five-year, transferable electronics warranty to give buyers extra piece of mind with their purchase.
