LowDown tone in a powerful and punchy combo.

The Line 6 LowDown LD400 Pro is a bass amp that offers venue-filling volume and LowDown tone in a powerful and punchy 2x10 combo package. Boasting a relentless, fully adjustable Rock tone, and 4 additional required tones ranging from R&B to Grind, the LD400 Pro bass amp offers power, versatility, and commanding tonal definition for the pro player.

The Line 6 LD400 amp also comes with a crucial set of 5 effects, led by a dedicated studio-quality compressor based on the LA-2A, and including a Smart Control FX Envelope Filter, Octaver, Chorus, and a full-featured bass Synth with fully adjustable parameters.

Designed for the gigging bassist, the LD400 Pro is a versatile amp that features an array of necessary ins, outs, and hardware, including an NL4M-series Speakon speaker output for an external cabinet, a balanced XLR direct output with exclusive A.I.R. processing, a 1/4" preamp output, and a pair of brawny 10" speakers ready to rattle some ribs and project your sound.

Amp Models:

Inspired by the Eden Traveler, this model is all about clean, funk, and fusion bass tone. It'll give you warm lows and punchy highs.


Inspired by a '68 B-15 Flip Top, this model is a tribute to those clean, fat, bass tones of the late 60's and early 70's. It is the kind of tone you hear on most Motown recordings, as played by the pioneering young bassist James Jamerson.


This model is inspired by the '74 Ampeg SVT which has appeared on innumerable recordings and arena stages worldwide. Now, all the tone of the head and 300-pound behemoth 8x10 cab is available without having to lookup a chiropractor.


Based on a '68 Marshall Super Bass, this model delivers the kind of overdriven bass sounds brought to us by late '60s British rock pioneers like Cream and The Who.


As the name would suggest, this is for the modern rock sound of the late '90s and the new millennium popular in bands like Alice in Chains, Mudvayne, and Rage Against The Machine. Based on a distorted SansAmp PSA-1 into an SVT with a direct clean bass signal mixed in, this model gives you that angry, clear, and punchy aggression that cuts through the mix and takes your sound to DEFCON 1.

Effects models:

This pro LA-2A-style compressor is ideal for helping every bass player - particularly the ones who play with their fingers -- achieve a smooth and consistent signal at any volume.

Envelope filter

Based on a Q-Tron, this envelope filter effect can be heard on tons of major funk and rock tunes.


Based on the EBS OctaBass, this effect produces a single note one octave below the note you're playing to add a powerful new vibe to your sound.


Based on the much loved T.C. Electronic Chorus, this transparent, smooth, and expressive chorus was built for bass, and using it won't reduce your low end. It's an especially beautiful complement for fretless basses.


Sitting at the back of the model knob is this secret weapon that turns LowDown into a '70s classic bass synth. From funk to modern rock, this fully adjustable synth delivers incredible tones while tracking every dynamic move you make.

Best Amp For Gigs and Practice!


from Undisclosed

Comments about Line 6 LowDown LD400 Pro 2x10" 400W Bass Combo Amp:

This amp has everything you would want in a combo amp. 400 watts, Direct out, Caster wheels, Handles on sides, Plenty of Effects and my favorite a Cd input for practice late at night! Playing rock and country I mainly use 2 of the amp models and 3 effects which I can program the sound and be ready before the song starts with touch of a button. 400 watts is more than enough for stage volume. The direct out allows me to connect right to PA board and it sounds massive in front of the stage!
