Overview

Melvin Lee Davis Bass Preamp & DI
We collaborated with American bass player (also vocalist, keyboard player, TV composer, and engineer) Melvin Lee Davis to create MLD Bass Preamp & DI. It has tons of functions based on Melvin Lee’s musical experience, and offers the best sound shaping controls such as 3- band EQ with middle-frequency selection, drive with blend control,  speaker cabinet simulation (Impulse Response file loader) and built-in noise gate with decay and threshold controls.
Audio Streaming and Recording
MLD Bass Preamp + DI can also be used as an audio interface. You can download and install the free NUX ASIO Driver, connect the pedal to your computer via USB, and use the headphone output on the pedal for monitoring, then it can send the bass guitar audio signal for recording. Simply you don’t have to use any other output on the pedal or computer.
NBP-5 Edit Software
You can control the pedal with the software and also load/change Impulse Response files.
Visit nuxefx.com and download the software for free.

Features:

• 3-band EQ with Middle-frequency selector
• Drive with blend control
