POD HD400 represents a giant leap forward for amp modeling. It is the only multi-effect pedal that boasts 16 brand-new, state-of-the-art Line 6 HD amp models, 90+ modern and vintage-styled M-class effects, and a comprehensive digital and analog I/O.

HD amp modeling: sound and feel like never before
HD amp models defy the accepted standard. They feel, behave, and interact with previously unachievable realism.

Creating these new HD amp models was no small feat. Line 6 mixed 15 years of amp modeling experience with 3 years of new research and development to build an entirely new amp modeling technology from the ground up. During that time, we hunted down 16 incredible amplifiers and”with the help of LA's top tube amp experts”restored each one back to peak condition. The new modeling technology uses 10 times more amplifier information than before, including single-ended class A tube stages, class AB push/pull interactions, power supply behavior, and more. The result is a high-quality warmth, feel, sustain, and articulation for you to fall in love with.

Tube amp fanatics have long enthused that their favorite stacks and combos aren't merely "amps," but instruments themselves, with playability equal to that of the guitar plugged into them. New HD modeling takes the POD HD experience to that same exalted level, capturing the genuine playability that great guitarists demand.

Your amp collection”now in HD
On the POD HD400's menu is a collection of freshly modeled amps, many of which are brand-new to POD, and all of which are essential for performing guitarists who require a wide variety of tones in one streamlined, multi-FX-sized package.

POD HD400 includes 16 HD amp models based on:
¢Fender Twin Reverb
¢Hiwatt Custom 100 (DR103)
¢Supro S6616
¢Gibson EH-185
¢Fender Bassman
¢Fender Blackface Deluxe Reverb
¢Divided by 13 JRT 9/15
¢Dr. Z Route 66
¢Vox AC-15

¢Marshall J-45 MkII
¢Park 75
¢Marshall JCM-800 (2204)
¢Bogner Uberschall
¢Mesa/Boogie Dual Rectifier
¢ENGL Fireball 100

90+ M-class FX
Made famous by Line 6 M13 and M9 Stompbox Modelers, M-class FX have found their way into the hearts of many musicians. POD HD400 features a whopping 90+ M-class effects to craft your sound. With this wide tonal palette to play with, you can sound like anyone under the sun, or no one but you. You can also use up to 4 FX at once.

¢45+ distortions (from classic stompbox distortion to thick metal chunk), EQs (from stomp comps and studio tube compression) and pitch FX
¢30+ analog and digital delays (including cool tube and solid-state tape echoes), echoes, wahs, and reverbs (from surfy springs, to studio plates, to cutting-edge digital rooms)
¢15+ swirly phasers, filters (including several exclusive custom filters) and other mods (including blackface-style opto and brownface bias-modulating tremolos, choruses, and rotary speakers)

The power of this collection is truly mind-boggling. In addition to these classic sounds themselves, POD HD400 functions as a fully featured looping, pitch shifting, and harmonizing machine. Ready to start creating? This rig could keep you going for a lifetime.

Unprecedented flexibility”stunning simplicity
Beyond the mere depth of the amp and FX models, POD HD400 offers flexibility to mix and match amps and pedals in multiple pre-set rigs, attainable at the stomp of a switch.

Line 6's engineer's worked tireless to make accessing this kind of deep programmability not tiring at all. Smart FX make it a snap to quickly dial in your tone, and the free, easy-to-use editor/librarian software supports your deepest, darkest tonal explorations. POD HD400 was designed by guitarists for guitarists.

Comprehensive connectivity for live and studio use
Put simply, POD HD400 connects to just about anything and everything”analog or digital, balanced or unbalanced, for amplification or recording.

A snapshot of the back panel shows 1/4" and XLR outputs (mono/stereo), USB, FX loop (mono/stereo), expression pedal input, a L6 LINK jack for seamless integration with Line 6 DT50 tube amplifiers, and more.

Built like a tank
POD HD400's cutting-edge technology is kept safe within a "bulletproof" bent sheet metal housing with heavy-duty metal footswitches and expression pedal. No injection-molded plastic boxes here”POD HD400 is ready to lap up years of road and stage abuse and keep you playing.

Version 1.3 Firmware update now available!
Power-boost your POD HD multi-effect with an additional six HD amp models and five amp parameters “ all for free in firmware update v1.3.

To get v1.3 just connect your POD HD via USB to your computer, run Line 6 Monkey Intelligent Updater and follow the instructions.

Firmware update v1.3 includes six HD amp models based on* channels from three classic American combos (the œVibrato channel of a Fender Deluxe Reverb, the œVibrato channel of a Fender Twin Reverb and the œBright channel of a Fender Bassman), two British half stacks (the œNormal channel of a Park 75 and the œNormal channel of a Marshall JTM-45 MkII) and a high-gain Line 6 original.

Five additional, fully adjustable amp parameters don each new HD amp model (and will be added to the HD amp models you already have). Further customize essential aspects of tube amp feel and behavior with Sag, Hum, Bias, Bias Excursion and Master Volume.

Meet the new HD amp models:

Blackface ˜Lux VIB
The œVibrato channel rounds out the HD model based on* the classic combo that' considered by many to be the ultimate studio amp: Fender Deluxe Reverb.

Blackface Double VIB
Fender Twin Reverb is an all-time classic of biting twang and shimmering clean tones. This model is based on* a Fender Twin Reverb œVibrato channel, which is a separate preamp circuit with clipping characteristics that are different than the œNormal channel due to an additional 12AX7 tube stage.

Tweed B-Man BRT
Based on* a Fender Bassman, the amp that started it all “ instant rock and roll tone. This model is based on the amp' œBright channel, which provides a different voicing from the œNormal channel by utilizing the second half of the first preamp tube. (The œNormal channel uses the first half only). High frequencies are increased due to the addition of a bright cap across the volume knob.

Brit J-45 NRM
This model is based on* a Marshall JTM-45 MkII, which marked the beginning of the distinctively bright and crunchy sound that Marshall amps are known for. The œNormal channel is adept at big, bold clean tones.

Brit P-75 NRM
Based on* the œNormal channel of a Park 75, a Jim Marshall-designed amp that enjoys cult status for its powerful Plexi-style tones. The œNormal channel delivers a slightly darker tone than the œBright channel, a model of which already appears in POD HD.

Line 6 Elektrik
A face-melting, soul-weeping Line 6 original with high-gain capacity, interactive presence and mid-range controls. Careful, this might hurt a little¦

Got this about 3 weeks ago and I love it. While I have no use for some of the amps and half the effects, the ability to customize my tone in my headphones then playing live through our system without ANY change in sound is the best. I've heard some complaints about not enough distortion. Let me just say, use the editing software and check out the custom tone section of the line6 site to checkout others custom tones. You may have to make some adjustments, but you'll find what you're looking for.

This version of the POD HD is not worth buying! The only differences between it and the hd300 is that it has an effects loop for adding addition effects (which is pretty much useless because all the effects you need are on this) and maybe twenty more effects, none of which you will need. I would save a hundred dollars and just buy the hd300, or pay a hundred extra for the hd500, which has much more possibilities of modifying tone, ect. I hope I was helpful

    These new hd pods are amazing sounding units. Believe me when I say this because I am a tube snob. I own a lot of good quality tube amps which I still use and will continue to do so. Live I'd rather log around a few amps to get the tones I love than having to settle for something else but this unit get me close enough to my tones. Only thing I miss is the onstage presence of my amps. Don't compare the amp models to the real amp being played in a room, compare it to what the real deal sounds like miked up and listen to how both sound in a mix. You'd find they are pretty close. The models are great sounding and for the price you pay I'd say this is a bargain deal and very easy on the back and leaves you with more room on stage. I've listened to and tried other units like boss, vox, digitech, axe fx, eleven rack and personally I prefer the line 6 tone and feel. In my books this is a great sounding amp by it self and is loaded with great sounding effects. All I can say is if you're on a budget and want great tone and something compact check out these units.

    Or even 2 stars..

    By Cibele Antunes Mendes

    from Belo Horizonte / Brazil

    First of all, this pedal board is big. I thought it wasn't that big but is very big, so check the dimensions first if you don't want any surprises. The presets are all sub par. I didn't go that far but maybe if you create your own presets it might sound a little better. The effects (FX) are ok, the chorus is ok, the flanger, phaser are ok, the delay is ok and there is a bunch of almost-useless effects that you probably never heard in any music in your life. So let's go to the point, in my case I wanted a pedal only for the FXs because I already have a distortion pedal and for the price I don't really think it worth the money. There are 3 banks of effects and you can't use 2 effects of the same bank at the same time, wich you CAN do with the HD500. I think the HD400 just doens't worth the money, go for the HD300 (they are almost the same but cost less), HD500, POD HD Desktop or the one those LINE6 Stompboxes, the M's series (M9, M13).

    So far, I have been very please with my Pod HD400. I'm an experienced musician just beginning to delve into the world of electric guitar (been playing bass and acoustic guitar for 10+ years). The Pod is very versatile and gives me any sound that I want.

    So far, everything is working great. The only complaint that I have about this device is the organization of the sound catalog. It is very easy to go from sound to sound, but with 32 banks of 4 sounds each, it can be daunting to remember which sounds work well together. Line6 has an accompanying software program that can be downloaded for free at their website to go along with the Pod HD400, but it doesn't help much. The software lets you create new sounds to take the place of current ones, but there is no (to my knowledge) way to move around existing sounds.

    On the plus side, it is very easy to modify the existing sounds. Once you get close to a sound you like, it's easy to tweak that and save it, overwriting the original settings for that channel.

    Overall, great sound versatility. I'm playing it through an Ibanez TBX150 and have been very pleased. To those who say the best effects come from a tube amp, I won't contest your statements, having not tried it myself. But for what I paid, the Pod HD400 is doing everything i want it to, and then some.

      A fellow musician turned me onto to the new line of Pod HD Products. I play a myriad of different styles as well as teach. I found that the HD400 is definitely designed to be a rocking beast with my Les Paul, but even sounds great with my jazz boxes. Obviously, it will never take the place of a good tube amp - but the technology gap is closing and I find myself just going direct into the PA, rather then lugging my amp around.

      I really enjoy all the extra room I have onstage these days!

      Take the time to learn how to use this POD!

      By Brian Moore

      from Michigan

      If you bring home the HD400 and just start "playing" with it, you could easily get frustrated. Instead, hook it up to your computer, download the Line 6 Monkey, and the editor. then sit with your guitar, POD, and computer with a set of headphones on. you can more easily tweek all of your settings on the computer instead of using the small function buttons. Once you have it set up, you export those settings to your POD and it saves. Admittedly, it has no distortion as good as the OD channel on my Marshall head, but the looper is amazing. I recently started playing lead, but this is the best practice tool EVER. you simply loop yourself playing rhythm, then find your lead sound and shred over yourself as long as you want. AWESOME!

      POD HD400

      By The Bretman

      from Iowa City, IA

      Other than the mode button's placement, this rig is almost perfect for someone like me, who needs quality amps and effects which are easily switchable, with plenty of connection options.
      This unit does exactly what I want a multi-fx unit to do, but it does have a HUGE learning curve. It doesn't come with a traditional owner's manual, but instead you can download it, along with some KILLER editing and calibrating software. Be sure when you get yours that you download the newest software version and any other stuff. The one problem I do have, (and this is because I've got big feet), is that when I'm playing live sometimes I'll accidentally hit the "mode" switch instead of channel A, and suddenly I'm in looper land, in the middle of a song! I wish there were a way to disable the mode switch. Perhaps make it an option when creating patches, like choosing an amp or effect. Trust me, if this happens to you while playing live it's a NIGHTMARE! Other than that one thing the features are great. Plenty of GREAT sounding amps, effects, ins & outs and options at your disposal. You'll need to take your time learning it though. Once you invest some quality time with the HD400, you'll be pretty happy with it.
      This thing is made of ALL METAL! The only plastic are the knobs, which are out of foot reach thanks to the metal handlebar above the footswitches. The footswitches are also metal, each with a lovely LED indicator, letting you know at a glance which patch, (A, B, C, or D), you're on. There are 3 modes. Channel, looper, and amp/effects. The channels are great. You get I think 32 banks of 4 channels each, (128 possible patches), customizeable to whatever you like. The looper is self-explanatory, and I don't use it. The amp/effect mode is cool if while in a patch you want to engage or disengage effects like distortion, chorus, or delay. You can also run up to 3 fx at once, PLUS reverb, noise gate, and wah, if you like. The expression pedal works quite well as a wah controller, volume, and effect morph pedal. Almost anything is possible here. The amp models are pretty darn convincing, as are the plethora of available effects. TONS of different distortions, compressors, modulation, delay, reberb, and wahs are available, plus noise gates and suppressors. Not to mention the choice of speaker cabs, microphones and mic placement options. Basically, if you can't find a tone you love on this rig, you're just not trying! You can plug this into a combo amp or a stack, or choose to run stereo direct to a live mixer or recording console, or to your computer via USB. You can even add your own stomp box and extra expression pedal if you like. All high quality connections, and all sound fantastic!
      For the price, this is a LOT of quality sounding amps and effects, connectible to anything you want, and all at your feet.

      Decent Effects "OK" modeling

      By Francis Fabrizio

      from New Jersey

      I have used the HD400 in lower volume jams with electronic drums, etc... It has good reverb, delay, wah isn't bad, but I agree that there is still a gap between real tube amp overdriven tone and this modeling..

      But you can't expect a 400 dollar pedal that has EVERYTHING packed in to replace your 2000 dollar Mesa Boogie Dual rectifier tone.. It's not there yet.. Closer than most others, but still not going to replace that. That being said, for a musician who just wants decent (not outstanding) tone and, this is important, the simplicity and ease to have everything just one foot click away, this is a good unit. Like I said, at lower volumes, you can achieve a nice mix with your band, but I played it once at a bar gig and quickly realized that like all multi-effects units, you cant' achieve the overdriven tube sound you "THINK" is there with your amp at 10 o'clock, but when you crank your amp up to, say 3 o'clock, you feel cheated by the "Thiness" of the tone...

      But I do like the processed sound at lower volumes....just not going to get you from basment to stage easily..


      What I've been waiting for

      By Jeffrey Jennings

      from Upstate, SC

      I've been a fan of Line6 since using the first Ax2 212. Line6 is the only company that was able to recreate the dynamics, sensitivity and "breathability" of tube amps. All the lower end modelers didn't come close. I feel the POD HD400 is going to last us a long time. So much tonal versatility! I have my favorite models, but they're all pretty neat. I don't use effects very often, and when I do, they're usually to mimic a specific part. That said, the effects are very flexible and sound great. The board is built with great quality and is extremely clean. Much more professional IMO than the busy glitsy Digitech style. Nothing against Digitech, because the RP1000 sounds good on Youtube as well -- just commenting on aesthetics. This is the first piece of gear that I'll use as a direct-out. I've played other processors and guitar amps with DI's and "cabinet simulators" but none have worked out until now. Last Sunday I went straight in with no amp. Monitored via Aviom in-ear system. Extremely convenient! The outputs are well thought-out too -- you get lots of flexibility for whether/not the cab/mic simulation is applied. Line6 should be sending kickbacks to Lincoln Brewster -- I have to think he's selling TONS of boards for them since he puts his POD patches on his website. The fact that Lincoln gets his killer tone from the POD is what tipped the scales for me. I'm a believer! I think Line6 really has their act together with modeling. Also love the editor software. Makes "getting to know" the processor much easier when you can see all the options laid out before you. Lastly, I was very worried I would wish I'd gotten the HD500 instead of the 400, but so far I really can't see the need for more stuff. I appreciate the sound flexibility of the 500, but my taste is pretty simple.


      POD HD400

      By The Bretman

      from Iowa City, IA

      After playing with the HD400 for a few weeks, (and a couple of live shows so far), I have come to LOVE this rig! The amp tones, (and isn't that what we really care about most?), are SPOT ON! The effects are serious as well, and best of all, they sound warm and alive. There is a bit of a learning curve here, but you have to expect that with any multi-effect unit. Once you learn the ins & outs you realize that this was VERY cleverly thought out and designed. It is solidly built of metal, including the switches, and I expect it to last many years, as my old POD 2.0 did. THAT unit, plus the old FB-4 footswitch was my rig for a solid 9 YEARS! I still have it too. But the HD400 is a quantum leap forward in amp modeling, and I could not be happier with the tones. Even my band mates - and people in the audience have told me that they loved my sound before, but now it's a whole other world! Get it. Learn it. Love it! I sure do!
      This rig is chock full of cool, useable features. Very realistic amp tones, great sounding stompbox style effects, a looper, and you can connect it to almost anything. Everything is right at your toes, and with some time becomes easy to run. My only gripe, (and this is just for someone like me), is that I wish you could somehow disengage the "Mode" footswitch. If you accidentally hit this while playing live you go into looper mode, and that can be troublesome. Other than that, this little unit is just dandy!
      So far I am very impressed with this well thought-out design. The housing and switches are ALL metal, though has plastic knobs. the readout is legible and easy to see, as are the LED's above the footswitches. It even has a handle on top, cleverly placed in front of the amp control knobs so your foot can't accidentally nudge the knobs while playing. The amp models sound VERY realistic, as do the effects. The distortion models are dead on, and even the choruses and flangers have a warmth that my old Boss pedals had. Line 6 really upped their game here!
      This kind of rig is meant for a guitarist who needs several different tones for playing live, as well as the connectivity for going to amps, mixers, and computers. The editing software is VERY cool and useful. For the price paid, I'm getting first class tones in a user-friendly, customizeable unit which is built like a tank. I expect many years of service with this rig. Not too shabby for the price.


      Great With Minor Flaws

      By Sutton Porth

      from Missouri

      So first off I love this thing. It sounds great through my amp and I am very satisfied. The amp models are pretty good but they are also pretty similar to each other. I can saw that I love the ENGL Fireball model though. The only reason that I didn't give it five stars is that the volume pedal isn't great it is pretty much an on/off pedal.
