The power you need, the sounds you want.

The Line 6 HD400 rack mount bass head, much like its LD400 Pro combo brother, offers LowDown tone in a powerful, rack-mountable amplifier. Boasting 5 fully adjustable essential tones, including Rock, Clean, R&B, Grind, and Brit, the LowDown HD400 amp head offers pro players uncompromising power, extraordinary versatility, and commanding tonal definition. The Line 6 HD400 bass amp head also comes with a crucial set of 5 effects, including a studio-quality compressor based on the immortal Teletronix LA-2A from the 60's, the Smart Control FX Envelope Filter, Octaver, Chorus, and a full-featured bass Synth with fully adjustable parameters.

The recipe for one great gig after another, night after night, the Line 6 HD400 is a bass amp head that features an array of ins, outs, and hardware like two NL4M-series Speakon speaker outputs, a balanced XLR direct output with exclusive A.I.R. processing, a 1/4" preamp output, an FBV jack, and rock-solid construction specifically designed to withstand life on the road.

Amp Models: Clean
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.

R&B
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.

Rock
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.

Brit
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.

Grind
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: Compressor
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.

Octaver
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.

Chorus
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.

Synth
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.

Awesome bass head

Posted by poit57 from Oklahoma City, OK on Aug 11, 2009

Experience w/product: I own it

Reviewer's Background: Active Musicion

Reviewer's Play Style: Rock/Alternative/Praise & Worship

I've only had it a day, but I am absolutely loving it. I upgraded from a Gallien Krueger Backline 600, which was okay for what I could aford at the time. I played through all of the presets, which has so much more than I could ever use, and found a few sounds that I will spend a majority of my time using.

I used to own an Alesis BassFX multi-effects pedal, but after much tweaking, I could still not always get the sound I was trying to achieve. Some of the presets are exactly what I was looking for in terms of sound.

I'm playing through one Kustom 4x10 cabinet, so I'm not using the amp to its full power potential, but it's still plenty loud for my purposes. The mp3 player input is also an added bonus over what I had before.

My purchase of this amp has made me very happy, and that is with much anticipation. I've been eying this thing since about 6 months before it was even released. It just took me until now to be able to afford it.
