NUX NBP-5 Melvin Lee Davis Bass Preamp & DI with IR Loader Pedal (NBP5 / NBP 5)

 

 

Designed by Bassist for Bass Lovers

We collaborated with American bass player Melvin Lee Davis to create 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.

 

 

Dual-Switch Action

It has independent controls for the looper and the drum: left footswitch (LOOP) controls recording, overdub, and start/stop of the looper. This switch also features the NUX Smart TAP function, which automatically detects whether you want to control the looper or set the tempo of the drum.

 


 

Melvin Lee Davis signature dual-switch pedal is:

A bass guitar preamp, DI box, impulse response (IR) loader and audio interface.

Yes, everything you need for practicing, gigging and recording is in the box!

A perfect solution for the performing singer/songwriter in you. Simply connect a dynamic microphone to the MIC input with adjustable gain control. Finally, adjust the on-board reverb effect for the microphone to make your performance come alive!

 


 

Closer Look

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.

 

 

DI Out, Auxiliary Input and Headphone Output

On the LEFT SIDE of the PEDAL, you can access the XLR output for a mixer and/or audio interface connection, and you have the option of activating the IR cabinet simulation.

There is a 1/8-inch (3.5mm) auxiliary input to connect a music player, and a headphone output for silent practicing or monitoring (please check the USB connection).

Headphone output is related to DI out; when you activate the DI IR simulation, headphone output will be simulated.

 


 

Firmware V3 & NBP-5 Edit Software

You can connect the pedal to your Windows / MAC computer to use the edit software: load your own IR files and control various other settings.

Supported IR file: 48 kHz / 24-bit, 1024 Samples

 

Bass Amplifier Models

MLD Bass Preamp + DI pedal comes with 3 amplifier models (Firmware V3), you can select and control the amps and the Noise Reduction on the software easily. There will be more amp models released . . . stay tuned !

 

Speaker Cabinet Models (IR)

There are 16 IR slots (8 factory / 8 user) in the Melvin Lee Davis Bass Preamp + DI(Firmware V3), and the pedal comes with the selection of speaker cabinet IR files created by NUX. Also there is an independent volume control for the cabinet simulation to adjust the IR level.

 

Drum & Loop on Edit Software:

For bassists, drum & loop is a great practice tool, so we add it into Firmware V3 with Edit Software. You can choose the Rhythm Style, use ⇧ / ⇩ to increase/decrease TEMPO, or TAP TEMPO. The Loop is auto-recording, which means while you engage the REC, it’s waiting for the input signal to start RECORDING.

Note: SPACE is the hot key of REC.

A driver-free* solution helps you produce music with direct connection. You can use the headphones output for monitoring, you will hear both your guitar and the audio from your computer.
