Feature:
It likes electricity. It should come with the adaptor for AC power, because no one will use the batteries for a concert and have it poop out half way through. It is well constructed and rugged. Well laid out and relatively easy to operate and control. All three pedals are solid and easy to operate.

Quality:
Rugged construction---hey it's a Boss.

Value:
For what is capable of doing, it is a great value in that all of the separate effects boxes needed to duplicate this would be hundreds more.

Desirability:
Nice looking unit

Sound:
I can achieve a warm tube that fills the auditorium. The sounds are nearly limitless. I play CCM for our church's band and this processor has changed our total sound because the bass is so much fuller. I wish that the synthesizers had a little more variety in sound, because they come off sounding just what their name says--synthesized. I am still fairly new with the ME-20B and am still exploring all of the different effects that are obtainable.

Ease of Use:
One evening and I had the major operations down. It makes perfect sense as to its lay out and operation and is to identify what mode you are in. Manual is clear and very useful.

Support:
N/A Haven't had to deal with questions or repairs.

Feature:
Not to much to say here. Great pedal. Basic features like tuner and such. Should have came with an adapter, however battery life is decent on it.

Quality:
Very sturdy. I dropped it a view times and it was fine. It even got rolled over by an 70 pound amp and was fine. Great for someone who might be traveling alot

Value:
I do believe that out of the pedals in this price range, this one is one of the best. There are some better multi fect pedals out there, but for the price, this one is excellent.

Desirability:
Really looks nice. Black and red and all shiny =]

Sound:
Really good pedal with alot of usefull effects. The only problem I had was that the preset wah effects are really quiet.

Ease of Use:
When I first got it, the EZ edit on it is pretty confusing, but besides that it is down to earth and simple. Turn knob and push button for effect. simple

Support:
Never used.

Overall:
Good pedal for someone who is looking to buy there frist multifect

Feature:
It dosent come with an ac addapter so I suggest getting one The same day you buy your petal.

Quality:
Its boss, its made great. no compliants on the design.

Value:
a great value!

Desirability:
I love the way it looks and feels, Its just a great addition to my setup.

Sound:
The sound I get from this pedal is great. It will make any amp louder, but some effects lack power ( moslty the preset lower octive effect) but other than that there are no compliants. It provides hours of entertianment. Its worth every penny.

Ease of Use:
Very easy to use, im still messing around with it though so im sure there is more I will discover.

Support:
didnt have any problem with the company that made it. It was shipped to me within three business days.

Overall:
Overall if your looking for somthing cheap but made good and worth every penny buy this petal.

Feature:
should hav drum beats, but ez edit makes up for dat

Quality:
boss=QUALITY, havent drop it yet thou

Value:
nice for the buck, as it is a boss, so its good

Desirability:
stompboxes actually ooze more sexy than multis but this thing looks compact that its sexy, like a sleek laptop

Sound:
synth should hav more range, wah should be warmer, maybe specific stompboxes can do the job, but its compact enough

Ease of Use:
fool-proof definately, easily get the sounds u want

Support:
theres warranty

Overall:
great boss product overall, im gonna gig with it soon, hope its all good. hoped for blue instead of red
