Designed by a Bassist for Bass Lovers. We collaborated with American bass player Melvin Lee Davis to create the NU-X MLD Bass Preamp & DI.
Melvin Lee Davis is an American bass player, vocalist, keyboard player, producer, TV composer and engineer based in Orange County, California. He is the music director for Grammy-award winning artist Chaka Khan and has recorded with The Pointer Sisters, Lee Ritenour, Bryan Ferry, Patti Austin and Gladys Knight & the Pips.
MLD Bass Preamp + DI has tons of functions based on Melvin Lee Davis' 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 loader) and built-in noise reduction with Decay and Threshold controls.

Features:
MLD signature Bass Preamp + DI features fully sweepable mid-range frequencies in addition to Bass and Treble controls. Melvin L. Davis is proficient at 4, 5, 6 and 7 string basses, so MLD Bass Preamp has a wide range of frequency control.
Volume Knob
Adjusts the overall output volume of the pedal. Ideal for fine-tuning the output on clean tone, it also controls the DI output volume.
 
Blend Knob
Adjusts to blend between the clean signal and overdrive signal. The clean signal remains as unity gain, allowing for fine control of the blend ration.
 
Drive Knob
Adjusts the Gain level and sets the saturation level in the overdriven signal.
 
3-Band Equalizer with Middle Frequency Selector
Bass: +/- 12dB @40Hz Middle: +/- 17dB @160Hz to 1000Hz Freq.: 160Hz ~ 1000Hz Treble: +/- 12dB @8000Hz
DI Output
Balanced XLR Output carrying the mic-level output signal, either affected or unaffected depending on the Pre-Post switch.
 
GND LFT (Ground / Lift) Toggle Switch
Disconnects the signal ground on the DI out to break any ground loops. Toggle the switch to the LESS noisy position; it can be either GND or LFT depending on the room, stage or studio condition. Switch does not effect the 1/4-inch (6.5mm) output.
 
Impulse Response (IR) Toggle Switches
You can activate/deactivate the IR cabinet simulation for both DI out and 1/4-inch (6.5mm) out separately. Use the appropriate IR toggle switch to turn ON/OFF the emulation for the output you choose.
 
Input/Output and USB Connections

Main OUT and Through
You can use the main "OUT" and "THROUGH" output to get the dry signal for bass amplifier connection.
When you activate the "OUT IR" cabinet simulation, you can connect the pedal to any FRFR speaker, directly to a mixer or audio interface. "THROUGH" output will remain bypassed either the "OUT IR" is activated or deactivated.
