Feature:
The presets rock bottom line. The ability to tweak and reconfigure the sounds is as easy as eating apple pie.

Quality:
Although the amp is relatively new it appears to be very well constructed. I will be using this "without a net" with my new band. I have faith. :-)

Value:
For the price this wins hands down. You WILL NEVER find another amp that does this for this price. If I lost it or it was stolen I'd have another one witin 24 hours. I wouldn't even look at anything else. (except mabe the Line 6 Spider III 150 head matched with a 2-12 Mesa Boogie cabinet with Blackface Celestions)

Desirability:
Had to have it as soon as I heard it.

Sound:
This has to be te most versatile amp made. The different sounds and tonal quality of this amp is far superior than any plain jane amp on the market today.

Ease of Use:
There hasn't been a sound that I haven't been able to recreate. It is that easy.

Support:
I ahve dealt with Line 6 in the past and thier support is great. Just go to their website and in the forums there are always people from LIne 6 answering any question you have.

Overall:
Don't need to search for another product, this is it.

Feature:
Twelve amp models and 400 presets....'nuff said. The phone jack and MP3 inputs are great for playing along to your own songs while the rest of the house sleeps. I've also hooked my Line 6 Guitar port up using the speaker out jack, to play music from my PC through the amp.

Quality:
Fit and finish were great...I was able to plug it in as soon as I got it and played for a couple of hours, without reading the manuals. (But of course, I'm a guy, so who needs a manual?) ;-)

Value:
Okay, a little pricy. How long it lasts (or I use it) will be the ultimate test. Had the 30 Watt Spider III had all the amp models and presets, I would have went that way and saved $100, but with all the extras you're getting on the 75 watt version I can't complain too much.

Desirability:
Very nice looking and it makes you look (and sound) like you know what you're doing, which is great.

Sound:
Many artist and sound presets, along with the ability to tweak what you got, or totally change any of several settings to get the sound you're looking for. This puts out A LOT of sound, enough to shake the walls, but has very clear sound on lower settings. Very nice to get a 12" celestion speaker with this. Makes my inexpensive guitar sound much better.

Ease of Use:
It takes some time to learn the subtle nuances of what all you can do with the output/settings/presets, but any shortcomings here are greatly outweighed by the superb features.

Support:
Haven't had a problem or reason to contact them on this amp, although my other experiences with them (Guitarport) they were excellent.

Overall:
A great sounding and playing amp. If you have the money get it, along with one of the foot pedals (so you can change channels as you play).

Feature:
It's all good. The A, B, C, D presets are great to store your sounds. You can even store each preset to the same volume, so you don't have to change volume every time you switch from clean to distortion or whatever. To set it all to the same volume, you have to keep the Master volume the same for all of them, and change the Channel volume for each preset so that they all have the same loudness (or quietness).

Quality:
It looks great, and it sounds great, and it's dependable. That's all you need in an amp!

Value:
This product is definitely worth its price!

Desirability:
It looks great, as I previously said.

Sound:
Great distortion, clean, and other effects, such as phasers, and delays, etc.

Ease of Use:
It's kinda laborious to scroll through the artists and songs presets, but it's well worth the effort to fix a sound to your liking.

Overall:
I'll keep this product for a long time. I'll be takin' care of this baby, and if you get it, you should too!

Feature:
Its got all these cool sound accessories that you would find in a pedal like reverb and chorus flange and delay. The 400+ presets is really sick too. You can plug your Ipod in, you can get a switch pedal (i reccomend it), you can record straight from it, it has a headphone jack. Its AMAZING.

Quality:
I bang this thing on walls, drop it often, sit on it, stack bigger amps on it, and it still looks brand new, no cosmetic blemishes on it. its such good quality.

Value:
For $270 this this is a steal. Its durable, has so many great functions and sounds, pretty lightweight for an amp if this size, and is just a great piece of equipment overall. A nice upgrade from my Behringher.

Desirability:
I think its better than any other amp like it except for the Marshall, but who wants to shell out like 1000$ for one anyways. This amp is the way to go.

Sound:
So good. 400 preset sounds and distortion anywhere from clean and insane. Chorus Flange, Phaser, Tremolo, Delay, Tape Echo, Sweep Echo, and Reverb. What could you ask for. Its also very LOUD. Hurts my ears at half volume. I'm scared to turn it up full.

Ease of Use:
Its slightly difficut to work you way around the presets, but soon you'll find a bunch that you love and be ble to get to them fast.

Support:
I have not dealt with them but I would imagine that they are pretty good.

Overall:
If this thing broke (I can't imagine how it would) i would immidiately go grab another one. I love this amp.

Feature:
Lots of features with this amp. probably more than I'll ever need or use but good to know they are there.

Quality:
The quality is excellent. Rugged design, good looks., this amp is made very well.

Value:
To me the Spider III is worth a lot more money. This is the first amp I've purchased in many years. Before then I had a few and well... they were amps without all the extra features. Big bang for the buck!! Don't hesitate. Buy a Spider and prepare to be blown away.

Desirability:
Well, I own it.

Sound:
Killer presets and great sound. You can easily tweak the sounds or create your own and save them.

Ease of Use:
Plug and play. select your sounds. It doesn't get any better or any easier than that..

Support:
They are the best. Just visit the Line6 web site and you'll see what I mean.

Overall:
I bought this amp mostly for studio recording. I'm definitely keeping it forever!!

Feature:
you'll get lost in the presets there is so many that you can use, tweak, and save em as your own.

Quality:
made to be very durable, it was lighter to pick up then i expected, theres pretty much no way you can break this thing.

Value:
it took me a while to save up for it but it's worth ALL of the wait for it.

Desirability:
very attractive amp.

Sound:
so many varietys of things that you can play anything from bark at the moon (ozzy) to hey joe(hendrix)and it get's realtivley loud for a 75 watt amp

Ease of Use:
this is so much better than a marshall stack which can take hours to dial in a good sound. but you'll have no problem whatsoever with the line 6 spider 3 setup. so many knobs which are easy to tweak to get the best sound possible for you.

Support:
very simple.

Overall:
i wouldn't trade it for anything beside a 120 or a 150 haha. :)

Feature:
no foot switch. but you dont need it. to many features to list.

Quality:
the best quality i have seen for a long time.

Value:
you would think this amp would sell for $500.00 but at zzounds it is 249.95 man what a deal!!! it is a deal.

Desirability:
it looks mean and it is mean. it well kicks some a--

Sound:
the best. sounds like any guitar player there is. or has been. just plug your guitar inn and sound like hendrix or srv or any guitar player no lie. you will i love it. the best thing ever been for the amp world. also sounds like any amp. it is a bad boy!!!

Ease of Use:
when you first get it it is a little hard to set. just read the book and then it is easy. to easy. just JUST READ THE BOOK!!!!

Support:
i bet it is good

Overall:
if it stops working to day. i will buy two more of them.

Feature:
Hundreds of modeled presets to go with whatever custom setup you can come up with on your own. Many presets are variations on overdrive, which has its uses, but not if metal isn't your thing. Built-in FX are OK except for tremolo, which, after daily amp use for weeks, still seems lame to me.

Quality:
Good quality for the money. Cabinet is sturdy, looks good, Celestion speaker handles whatever I've thrown at it. Not even a hint of a glitch with the electronics. Digital modeling is probably the wave of the future, and Line6 has done that part right.

Value:
Great bang for your amplifier buck. Good sound straight-up, plenty of FX, power for most situations, and volume aplenty. It looks like lots of other amps, but I paid for performance, and looks don't matter in that category.

Desirability:
If versatility in terms of sound or playing style is important to you, the Line6 Spiders deserve consideration. The sheer number of FX available is fun to play around with, and you're sure to find at least a handful that you'll want to use often.

Sound:
Good sound quality - plenty crunchy when that's what you want, enough distortion to make your ears ring, and squeaky-clean when that's what you want. Plenty of volume for any but really big rooms (and you'll be using their sound system if that's the case anyway). Some settings sound a little bit "reedy" to me, but overall it's solid.

Ease of Use:
Tons of features, but not all that easy to use. Setting up your own sound is easy and straightforward - dial in what you want, play it, and tweak from there. Using the modeled presets ought to be MUCH easier than it is. If you know you like preset 'x,' it'll take you 10 minutes to find it, and finding it doesn't get any easier or faster with use.

Support:
Don't really know - haven't had to deal with them.

Overall:
The Line6 Spider III has features my other amp, which is 15 years old, can't match. It's solidly constructed and produces good tone and volume. It's not as easy to use some of the features as it ought to be, but the features are there, nonetheless, if you want to use 'em.

Feature:
Amazing presets

Quality:
no cover on the back. otherwise great.

Value:
deff. worth the price. great to mess around with

Desirability:
sexy

Sound:
Great distortion and everything. Clean sound is a little strange. Overall, really great.

Ease of Use:
The best. Sounds better on clean with a chorus pedal though.

Support:
sent in the warranty. thats it though.

Overall:
very satisfied. i recommend a chorus pedal
