Livero B20 Professional Bass Guitar Combo Amplifier

The B20 is a powerful yet compact 20-watt professional bass guitar combo amplifier, ideal for home practice, small rehearsals, or bedroom sessions with plenty of headroom. It delivers clean, tight bass tones with ultra-low distortion (0.1% THD) through its responsive 8-inch 8Ω speaker. The added Gain control lets you drive the input for warmer overdriven sounds when needed, while the parametric mid EQ (with Frequency and Level knobs) gives you precise control to sculpt your tone—perfect for cutting through or adding punch exactly where you want it.

Tone shaping is effortless with dedicated Bass, Treble, and Master Volume controls, making it easy to dial in everything from deep lows to bright slap tones. Practical features include a standard instrument input, 3.5mm AUX input for jamming along with tracks from your phone, and a 3.5mm headphone jack for silent practice anytime. Its sturdy, portable design makes it a great step-up from smaller amps without taking up too much space.

Whether you’re a beginner building skills or an experienced bassist needing a reliable, tone-rich practice amp, the B20 offers professional-grade EQ flexibility and clear power in an affordable, easy-to-use package that inspires great playing every session.
