NUX's MLD Bass Preamp + DI has tons of functions based on American bass player Melvin Lee Davis' musical experience, offering sound-shaping controls such as 3-band EQ with middle-frequency section, drive with blend control, speaker cabinet simulation (Impulse Response loader) and built-in noise reduction with Decay and Threshold controls. The Melvin Lee Davis signature dual-switch pedal is a bass guitar preamp, DI box, impulse response (IR) loader and audio interface. It features fully sweepable mid-range frequencies in addition to Bass and Treble controls with a wide range of frequency control.
