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.

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.

Recording With Melvin Lee Davis Bass Preamp

You can record your bass guitar without using any audio interface. MLD Bass Preamp + DI has a built-in audio streaming function, so you can connect the pedal directly to your computer with a Micro B USB cable, and it is ready to play and record. A driver free* solution that helps you to 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.

PLEASE NOTE: Run the audio recording software first, then run the MLD Bass Preamp Editor Software to use it properly.

Signal Routing

There are 3 ROUTING OPTIONS for the USB audio streaming:

NORMAL: You can create your tone by using the pedal, and it will send the processed signal to the recording software. DRY OUT: You can record your bass guitar without any preamp effect and IR simulation. This option is useful for re-amping. REAMP: You can playback a recorded track on the recording software, and send it to another track. MLD Preamp will process the signal while recording to a new track. (see: Re-amp Routing)
