HAO's "BASS LINER" is a high-quality bass preamp/5-band EQ pedal highly regarded in professional settings. It boasts a delicate and clear sound quality, bringing out the full resonance of the bass even in a flat setting. Using carefully selected components, it achieves low noise and a wide-range sound. Equipped with a very powerful 5-band equalizer (Hi-MID, LO-MID, BASS, TREBLE, PRESENCE, etc.), it allows for intuitive sound shaping from fine details to dynamic correction. With a direct out (XLR connector), it's also powerful for sending to PA systems in live venues and in recording environments. This is an essential unit for upgrading your bass sound to a professional level without compromising the bass's original tone.
