Description
The NuX MLD Bass Preamp + DI, developed with bassist Melvin Lee Davis, is a versatile all-in-one pedal combining a preamp, DI box, IR loader, and USB audio interface. It features a 3-band EQ with a sweepable midrange, blendable overdrive, and impulse response cabinet simulation. With multiple output options, built-in noise reduction, and direct USB recording, it’s ideal for live performance, studio use, and silent practice. The included editor software allows detailed tone shaping, IR management, amp modeling, and loop-based practice tools.
