Feature:
This guitar is an achievement on a number of levels. Typically new technologies such as this go through countless models to reach a working solution, usually leaving the equipment buying masses to pay the tab. Line 6 did an outstanding job of keeping this under wraps until they could produce an instrument that really does everything it claims.

Quality:
I've always had concerns about Asian manufactured guitars, but his Korean made guitar is top notch. Good wood, good cuts, good fittings. Well beyond anything I've seen from them in a while. Anybody remember Hondo guitars???

Value:
I bought this guitar for $200 less than it is currently advertised here. I would definitely say the cost versus value is well balanced.

Desirability:
This is a badass piece of equipment and it will definitely attact attention. It is a technical marvel and if thats not good enough, the fact that it has no pickups will definitely start a conversation. Very lust-worthy...

Sound:
Not only is the thing a technical marvel, it really is a sweet playing guitar. Great action, very "soft" and playable.

Support:
Haven't needed any service but questions can be answered quite readily via the Line 6 website.

Overall:
Without the wall wart the thing uses 8 AA batteries or a 9 volt by itself in an emergency. Can't say I care for that, but I know the engineers tried to make reasonable accomodation for power consumption - after all the thing is a guitar with a processor built inside the body. All of this can forgotten about should you choose to purchase one of the new Line 6 amps which use the proprietary variax cable to power the guitar. All in all, the way this thing plays with nothing plugged in was enough to make me buy it. Beautiful playing guitar.

Feature:
The stock neck... If you like playing huge fretwires (think railroad spikes) go for it. The neck exhausted me, so I replaced it. Now, I am a very happy camper.

Quality:
This 500 series is ugly. The black and red models are atrocious. The sunburst I bought is tolerable. Nothing fancy in the guitar... if you want beauty, buy the 700. If you just want an amazing axe, the 500 will do. Plan on replacing the neck either way.

Value:
Considering what you get, and what you can do with it, it is superb. I paid $850 for my 500; now you can get them cheaper.

Desirability:
Sound/tone: 10+ Body appearance: 7 Average: 9.5, only because the flexibility in tones/sounds/instruments is staggering.

Sound:
Nothing else compares in any way to the sounds you can get out of this axe. Are each of the virtual guitars perfectly accurate with the "original" - no, but are they close enough to provide a professional sounding array of sounds and tones... absolutely.

Feature:
Can't ask for more

Quality:
Neck is dove-tailed at 3rd fret and it looks crummy. Neck already warped and started to buzz after 1 month, had to adjust releif. Frets could have been finished better.

Value:
It's more of an interesting toy than a really playable musical instrument. More money than an American Strat, not half as playable. Does offer a lot of interesting electric guitar sounds

Desirability:
Have it, wish I hadn't spent the money

Sound:
Electric sounds are ok except for the 12-strings, they sound like a chorus effect. The acoustic sounds, including banjo & resonators, are not realistic at all. Fun to mess around.

Support:
Have not needed it but their web-site could offer more information, be easier to navigate, and stress support (which it doesn't)

Overall:
I'll keep it and probably replace the neck, which raises the price $150. Hopefully Line 6 will have a software upgrade.
