Feature:
JUST what I needed! Not too many bells and whistles, but WAY more than you'd think by looking at the panel. For example, you can change cabinets by pushing in and turning the amp model knob! Soo much is here!

Quality:
It aint' tubes, but you won't be changing the glass every 6 months, either!

Value:
Perhaps a little overpriced for a solid-state unit, but I guess we're paying for the R&D... ; )

Sound:
REALLY brings out the nuances and differences from guitar to guitar. VERY detailed, and can be IRRITATINGLY so until you "iron out" the EQ for your particular rig/guitar/cabinet combo...

Support:
I have no experience with this except through their website. I've owned LOTS of Line 6 products, and still have an Original POD Pro, which has worked GREAT and never required service...

Feature:
Tons of different features although... one of the footboards are required to make it probable in a live setting.

Quality:
I had one issue so far that was my fault (beer in amp = bad). Aside from that the screen on my footpedal died. That is not a bad point for the HD147 but is for Line6.

Value:
With all the different tones at your fingertips you cannot go wrong if you need all this power. I use mine for recording (not live) and it is overkill.

Desirability:
For a live rig, with stereo XLR outs it is an engineers dream.

Sound:
It truly does sound great, not tube great though. Clean channels can be quite amazing.

Ease of Use:
Very easy for the most part. You must use the computer software to setup mic emulation which is a small bummer.

Support:
Have not used it...

Overall:
I will replace with a KB37 simply for the fact that I only use it for recording. If I did not have a favorite live rig already then I would use this for both.

Quality:
i travel a lot and it comes with me every where i go. it's taken some hard fall and it keeps on kickin it.

Desirability:
a thing of beauty on a dark stage

Sound:
crisp and clean, thick and crunchy

Overall:
if i had to be stranded on an island with one thing. it would be this head.

Feature:
I never see anybody rating the the capabilities of the back of this amp , Threw Midi, I've connected this head to my PC, Installed Line 6 Edit and your options to this amp are basically endless, The interface looks just like the front of the amp , You can control an aray of things from the software, Hmm can Marshall amps , Krank amps, Or to mention any other amp do this ? NOT to my knowledge, The direct out is just extraordinary, When connected to a mixer , And ran into a Pro Tools arrangement ...

Quality:
This amp is built like a tank , I am extremely carefull around mine, just simply because i look forward to having this thing working prestinely for years to come . And i trust it will.....

Value:
At a glance the price is a little steep , But after owning this amp and seeing what it is capable of , Well worth the money , If your a serious musician ...

Desirability:
Man , This amp has a "CHROME" Chassis , I've had people compliment just that image alone ....

Sound:
Let me tell you something , HANDS DOWN this is the best sounding amp head on the market for the money . You can accomplist anything from Blues, Country,Classic Rock, Rock,Hard Rock, Punk Rock,Heavy Metal,Thrash Metal, And yes even Death Metal, Your average Marshall JCM 800 is far from accomplishing this... KRANK amps may give them a run for the gain sounds , But you will still need some kind of external effects to catch up to what the HD 147 contains .......

Ease of Use:
The only gripe i have on this amp is that without useing the software , I can see where someone might run into a little confusion, But with a little patience you'll hit that sweet sound guarenteed ...

Support:
Im gonna rate this a 9 seeings i haven't had to use it yet .

Overall:
I won't search for another amp , I have the sound i've always wanted , I'm 35 and been playing guitar for 21 years, So far NO amp has caught my attention more than this one , Not even the VETTA II, In fact i really want to by a back up , Just in case something happens to this one , Lets face it , "Nothing Lasts Forever", I play a modern melodic heavy metal style of music and this amp can go even beyond my realm ...

Feature:
Contains a bunch of great heavy amp models. If only it contained Line 6's other heavy amp models like the JMP-1 or the Rectifiers. It also needs better reverb, more modulation and delay effects, an effects loop that can handle both stompboxes and rack equipment, and even some synth effects. Then it would be complete.

Quality:
If it's Line 6, you bet it has good quality. This is definitely built to last!

Value:
This product is worth every penny. Why go for just one kind of amp sound when you can work with several of them. This is by far the king of heavy metal amps.

Desirability:
This thing is the coolest looking amp on the planet (well, almost). You gotta love those black lights on the inside. This is not an amp - it's a rrrrrrrrr institution!

Sound:
The sound quality of these amp models is just astounding. The cleans are just superb and the distorted models are just plain heavy. Line 6 never done anything like this before and it's about time they did.

Support:
Line 6 is the best in terms of support. They really know what they are doing. If only they would fire their accountant so their products were cheaper to buy.

Overall:
I am overall very satisfied with this product. It may cost an arm and a leg, but this is definitely worth the expense. Line 6 once again delivers a great amp. They gotta use all of these models on their Vetta!

Feature:
So many features, so little time.

Quality:
It will be a great buy if you dont want to buy 20 amps and a room full of pedals.

Value:
Great Value.

Desirability:
OMG What can I say!

Sound:
It's absolutely astonishing. I didn't think that tube tone was posible through a computer!

Support:
I haven't owned it so I dont know but they answer my email questions.

Overall:
A Great amp, compares well to Mesa, Bogner, Diezel, and Marshall.

Feature:
I liked how easy it was to change amp models and cab models. There seemed to be an almost endless combonation.

Quality:
Well, I'm one of the unlucky ones. It's as if my fell off the back of the shipping truck. I have multiple Major problems. 1) All of the stereo effects didn't work right: they were all mono and corrupted. However, they worked with headphones. 2)Mine always shocks you. Not a sudden shock, but a constant steady unending electrocution. 3)About once every hour I hear this incredibly loud POP!! and all the lights on the amp go off and on.

Value:
It took me a whole to save up for this amp, because I have rent, truck payment, etc... This was a major let-down.

Sound:
I have an Ibanez with Evolution pickups and the sound is very good.

Ease of Use:
Fair, but you'll find yourself reading the manual.

Support:
Their tech-support will remind you of when have computer problems and you call the tech-support and they tell you to run disc-defrag and a scandisk. Of course that never fixes anything. First, they said that the popping sound must be my guitar cord, though I had tried about 8 different cords. Then, they said that I must have a bad power supply in the house. However, I've used this amp at many different houses and had the same problems. Anyway, it was under warranty. Problem solved right??? Um no... There wasn't a electronics shop anywhere in my area that fixed Line6 amps. So, the tech-support said I needed to send it to Lee Summit Missouri wich was about 300 miles away. I didn't have time for that and I decided to pawn for $400.
