Overview

Melvin Lee Davis Bass Preamp & DI
We collaborated with American bass player (also vocalist, keyboard player, TV composer, 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, 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
• Built-in noise gate
• Impulse Response loader, speaker cabinet simulation
• Versatile input and output options
• Firmware updates, software control, audio stream

• Input to DI Signal Routing Toggle
  

If you want to use the DI out without using the preamp, you can set the toggle to PRE. The input signal will be delivered to DI output directly.
Or you can set the toggle to POST to use the preamp and drive functions for DI out connection. No matter the PRE or the POST is selected, you can activate/deactivate the speaker cabinet simulation using the DI Toggle.

• **Ground Lift Toggle

**

If you meet ground loop noise issue, it helps you to eliminate the hum noise.

• 1/4″ Through Output
  Dry signal output, if you want to connect the pedal to the amplifier in front. You can avoid the pedal’s preamp section and use the amplifier’s preamp. Speaker cabinet simulation is not supported.

• 1/4″ Main Output
  The main output. You can get the processed sound from preamp/drive section. Speaker cabinet simulation can be activated/ deactivated.

• Micro B USB
