Feature:
Just a USB cable and CD software. The software is the key to the usefulness of this device as the tones and tools such as metronome and tuner are part of the software interface.

Quality:
Looks very well made - haven't owned and used it long enough to test durability. It looks solid.

Value:
For a practice tool, this is great as long as you have a computer to support it. It WILL NOT work without a computer so you are tied to either you desktop or laptop and you must also have an internet connection for the services. Nevertheless, it fulfills my current requirement for a fun little practice tool.

Desirability:
I like the compactness and the layout of input and output jacks and volume control

Sound:
For practice and familiarization with effects, this is great. Lots of sound variants, tones are very close to the sound you hear on recordings by artists like Hendrix.

Ease of Use:
Very intuitive interface. Easy to change and modify tones. Lends itself to experimentation. Sounds great over headphones and I assume external speakers.

Support:
Have not had need to contact the company. Some problems with connecting to the services that interact with the Guitarport. There is a user discussion forum that is helpful.

Overall:
Will keep this as long as I play as it meets my needs. Maybe a stomp box or pedal effect would replace it. I would definitely buy a replacement if it breaks out of warranty or is lost or stolen.

Feature:
Incredible versatility! Great sounds. Little limited due to copyright issues though. But its the best tool I have seen for guitar. I would like to see direct recording without buying add on, and print functions.

Quality:
Looks great. Built sturdy. Input jacks are well protected in the rear.

Value:
for 99 bucks, this will replace quite a but of equipment, cut practice and learning time, and can be used as amp model with a PA. With the optional $79 a year website membership, you will eliminate the need to buy TAB books.

Desirability:
I never put much in looks of equipment, if the equipment works as or better than I need or expect, I use it.

Sound:
Ever want to have all the classic sounds at your fingertips? Cant quite get that VH sound you want? Get this! You will love it.

Support:
Have not needed

Overall:
As long as the current level of dedication from Line6 is maintained, the usefulness is endless. I would be likely to buy an upgrade, or additional item with added features.

Feature:
Guitarport can do more to your your guitar sound ("tones" as line-6 calls them) than piles of pedals and racks of very expensive effects processors. Albeit, it needs your expensive computer, which you probably don't want to lug to gigs or rehersals, do you? It integrated perfectly into my PC, leaving the soundcard and other peripherals unaffected, and they are all happily working together. Note: I jacked up the guitar-port quality (there is a simple control panel), the USB signal, and reduced the latency. This is supposed to make it sound all the better. I couldn't notice a difference in sound, but my machine (2.6Ghz, 512Mb SDRAM) is barely sweating the guitar-port's max system load (it's always between 10%-15%). If you have a PC already, this thing is great and works better than you might imagine and BETTER than advertised. If you don't have a guitar-port (and have a newish computer) you are a self-righteous snob living in a tube-amp fairy-tale, or are really poor and need to get a better job. It's only $99!

Quality:
Well, it's not perfect, in fact it's fake. Sometimes you can actually tell, most of the time you can't, unless you are the tube-amp-fairy. It's really good fake. Everyone should get one. If you really, really want a "real tone" only play acoustic. Honest purists wouldn't play an electric guitar at all. Ancient amplified guitars, vintage vibrato and spring reverb are just as fake as guitar port. In fact they sound worse. You purist loosers must flee before my acoustical logic! Put it this way boys: if you see a girl looking just the way you like, but you think parts might be fake, do you stop looking? Would you forgive her if she confesses to you? If it's good, it's good!

Value:
This is the best thing I have seen in music at all, and will be for years to come. It helps the open-minded guitarist select and listen to himself playing through almost every conceivable tone. You can learn what sounds (I mean "tones") you want and like, and guitar port delivers them in a VERY simple and flexible package. It can help a true artist find their "voice" in the privacy of their own room, without mockery from tube-amp purists OR complaints from upstairs neighbors (yes, there is a built-in headphone jack).

Desirability:
The actual Guitar Port box is wierd looking and keeps getting underfoot if it is on the floor, and falling off the amp or table. Bad physical design. Plus: candy apple red is sooo wanna be cool. It really good as a device, but a flop as a fashion accessory. SO WHAT!

Sound:
This thing sounds great, and it does a very close imitation of everything I have tried to make it do, but don't be fooled, it is not a 100% replacement for a tube amp sound. It is a 98% replacement, and a 100% effects-processor. I will comment at various times on the tube-amp sound in the following. Sadly, it does not do a "real acoustic" sound (as far as I can tell) unlike the other "variax" line-6 products, which sound pretty darned good. :(

Support:
You must pay for the guitar-port "online" experience. This REQUIRES a credit-card. Most teens don't have one, thus the "online" crap is a greedy way to make steady cash ($8/month or $96/ year) for line-6. Most of all, I have heard that it is near-impossible to cancel the service once you start paying for it. The actual guitar-port tool is great, why do they mess it up with a crooked online business? A little hint: just buy the thing, ignore the online pay - BUT go the the "wrong" section : the one for pod-xt "tone" downloads. These work fine on my guitarport. You are going to need to tweak the sounds once you get them, anyways. There are 1000's of online guitar tabs and tips online to help you learn, so ignore the lessons, unless you like getting trapped in a credit-card loop and paying $100/year forever.

Overall:
A little more work from line-6 and I will order this thing for my friends and family to play on. If line-6 keeps upgrading the software, it will be new and useful for years. Easily the best $100 I have spent on anything musical ever. No kidding.

The Guitarport makes it incredibly easy to record professional-quality guitar audio on a home computer (with additional software). Within a half-hour of receiving the package from UPS, I was recording very realistic guitar tracks in Cakewalk Pro Audio 9.03. I have run into a few problems with configurations, but I was able to fix them without too much hassle - overall, this is an excellent product at an unbelievable price. I don't plan on checking out the Guitarport Online any time soon, because that really wasn't what I was interested in, but it does look promising.

Sound:
For a measly $100 who could complain. It is the best money I've spent on a piece of gear lately. Paying with my Dimarzio equipped Dean I find the sounds to be acurate enough to play the Online downloads. The Floyd and Sabbath songs sound great with Super Distortion bridge pickup. I use my Tone Pro neck pickup for Clapton and SRV. It is a fun toy and I totally enjoy using it. It got me playing a lot more than I had been lately.

If you are sometimes stuck without someone to jam with, or maybe your solo practice sesssions have bcome a little stale...This thing will rock your world. Combine Line 6's famous amp modeling with an interactive website and tricky litle piece of hardware. It's just too cool!

Best eductional tool ever for playing guitar. Slao gives you the versatility to do just about anything with the sound output. Its awesome!

Great product, a little pricey, but will pay for itself soon...
