Feature:
There are lots of effects on board. The reverb, chorus, and echo features are useful. I also use the compressor and noise gate with high gain models. Anyway, pretty much any type of effect you need is built in. There's no foot control included so you have to part with some cash for that. You can pick up a used short board on ebay at a reasonable price. Unless you use a lot of different combinations of tones and effects you can pick up the original 4 channel foot switch real cheap. (Originally $100.00 and now discontinued)

Quality:
This amp seems to be very solid. The grill covering and tolex seem to be highly durable. The switches and jacks seem to be high quality. The only weak link is the foot controller connection. Not that I've had a problem, but it is a standard ethernet cable with rj45 connections at both ends.

Value:
This amp is a little pricey. It won't hold it's value like a tube amp. Especially with a one yr warranty.

Sound:
The Fender models are a dissapointment. The highs are too thin and the lows a little mushy. The Marshall models are OK but the best tones are in the Line 6 models (clean, mood, & insane)

Ease of Use:
As far as ease of use, you have to study the manual for a while. Each amp model will respond differently To eq and volume. Once you find a tone,effects,& volume combination that you like you can lock it in for recall. There are 4 preset buttons on the amp which correspond to the 4 button foot switch.

Support:
Line 6 support is very helpful. They respond quickly to email, and honor warranty claims, although the 1yr warranty is too short.

Feature:
NOT ONLY ARE THE AMP MODELS GREAT, THERE ARE AWESOME EFFECTS THAT WHEN USED WITH THE MODELS, YOU CAN GET ANY SOUND YOU CAN IMAGINE , THE ROTARY SPEAKER EFFECT IS SO AWESOME!!

Quality:
GREAT QUALITY

Value:
COMPARED TO OTHER AMPS IT'S A GREAT VALUE, BECAUSE WITH THIS AMP YOU HAVE IT ALL.

Desirability:
IT MAKES YOU SOUND BETTER THAN YOU ARE , IT'S MY FAVORITE AMP EVER,AND I HAVE OTHER AMPS ,PEAVY ,CRATE,AMPEG,& HUGHES & KETTNER, AND THIS IS THE AMP I ALWAYS USE.

Sound:

Support:
HAVEN'T HAD TO USE SUPPORT

Overall:
IT EXCEEDED MY EXPECTATIONS, I WOULD BUY IT AGAIN, AND PLAN TO BUY AN EXTENSION CAB

Feature:
Plenty

Quality:
well built, solid feel

Value:
No $600 amp on the market can compete

Desirability:
Good sound, good looks

Sound:
Rich, full,versatile...always satisfying

Support:
Havent had to use it -- which is the best kind!!

Overall:
Awesome

Value:
Best on the market!

Overall:
This thing sounded so good and flexible that I've bought this over the Marshall TSL and DSL amps. Everyone I played with was amazed at how good is the sound. The only downside is it's too heavy to bring around. But for quality and value, you won't be disappointed!

Feature:
Plenty of features but still simple to use. I compared to Fender Cyber Deluxe, which requires a pilot's license to operate. One feature I wish it had is touch wah, which is why I dock it a couple of points here. Waaaah.

Quality:
Time will tell but this seems solid and well built. Very elegant look, imho. Not at all cheesy like the teen-oriented Spider series. This looks and feels like it was made for grownups.

Value:
The amp itself seems reasonably priced BUT THE OPTIONAL FLOORBOARD IS RIDICULOUS AT ALMOST HALF AS MUCH. IT'S GOUGING PLAIN AND SIMPLE.

Desirability:
Tube snobs may sneer but this is a nice looking and good sounding all-in-one amp. No one yet seems to do the modeling thing better than Line6. This rig is ideal for home use, jamming and light gigging.

Sound:
Deep rich sound for solid state; amp/cab sims are very good. No it's not a tube amp, so 9 is the best rating it can get.

Feature:
Can't slag the features, it has loads, and most of them would be entirely useful if not for the aforementioned problem.

Quality:
The Achilles heal of the amp, in my opinion not very well made and the mushy distortion just kind of kill any enthusiasm for the amp.

Value:
good price

Desirability:
Nope I play live and this amp does not cut it at all.

Sound:
Bought this amp after an hour of messing around at the store. Big mistake!! Although this has a tonne of tones, it's the low end that is the deal breaker. It gets very woofy and mushy. No definition at all, I play mostly rock, classic rock and and kind of palm muting will show this problem.

Ease of Use:
It is very simple to use, especially with the FBV express or shortboard

Support:
Did not deal with them

Overall:
If they fixed that low end mushy distortion, in combination with the awesome cleans on this amp it would be well worth the money.
