Feature:
this is an entire pedalboard in one package. everything you could want is in included (well, no wah but i dont use that anyway). compressors, modulations, delays, an awesome loooper, reverbs, filters.... its everything, all in one package. the only thing i had to add was an actual pedalboard to house and protect it. you don't need to buy a powered board either which will save you around $100 since the included wire is quite long.

Quality:
this pedal is pretty rugged. all metal housing, all metal footswitches and a roll bar. this pedal would be great on the road, but like i said i bought a hardshell case just to make sure the screens dont get damaged. god forbid something fell and cracked one of the screens while you were driving to a gig or whatever. thats probably the only weak point, but its not because of shotty workmanship. screens are screens.

Value:
best bang for your buck. i would have paid more than the $500 i did for this thing. its just got so much. your not gonna need every effect it has to offer, but it feels good knowing if i ever need it it's there. and the effects i use frequently are absolutely great. if you read this much, buy it. you'll love it.

Sound:
i've spent some time and some serious money building a respectable guitar rig. i own a gibson explorer, and a gibson sg standard. my amp is the new marshall jvm 210h which i run through a marshall 1960a cab. my last move was to build a pedal board for my rig, but after discovering this thing there was no reason to go any further. this whole unit is 24 bit which is clearer than cd quality (thats only 16 bit) and it shows. the sound is top notch. all the the effects modeling is really good, and gives you not only the newest and best version of each effect but lets you dial in all the old ones too. i agree, if you have a good amp with good distortion you probably won't need the distortions this pedal has, but the compressors that are in the distortion modeling are really good and can really sweeten your overall tone. this is the best piece of gear i've bought in years. and considering you could spend well over $1500 for all of its counterparts, the price is actually a steal. this unit is really quiet, and it does not substantially degrade your tone which wiring numerous pedals together inevitably does. i love it.

Ease of Use:
the beauty with this is it really is as easy as the "bonehead simple" rating suggests. and with each effect (and optional expression pedal) it also gives you the flexibility to really tweak and create your sound.

Support:
i have a bunch of line 6 stuff and to date nothing has broken that i didnt accidentally break myself. i have emailed line 6 and they are very good at answering quickly. they were giving away expression pedals during the time i bought this product and line 6 was good enough to email me a few times to let me know due to the volume of free pedals they were giving away i would have to wait another few weeks but was not forgotten about. i thought that was kinda cool.
