Feature:
Being able to store and retrieve patches is why I bought this. It seems to work just fine and has plenty of parameters for my interests. A previous reviewer panned it because he could not tweak his settings, and his comments nearly stopped me from buying it. But page E15 of the manual explains how to see current patch settings and it's not difficult to edit them after they've been stored.

Quality:
Seems quite solid and sturdy. Has an all metal case. It does not have a "cheap" feel to it, and is pretty heavy.

Value:
$300 seems like a very fair price. I did not do a lot of comparison shopping though. The ME-70 was recommended to me and I liked what I saw.

Desirability:
I'm happy to have it, but perhaps I lack enough enthusiasm to find it sexually appealing.

Sound:
I don't have a huge experience with effect pedals, so I may not notice nuances critical to a serious professional, but I am perfectly satisfied with the sound quality of this pedal.

Ease of Use:
Easy to use without the instructions (which are too spare), but they seem to cover the programming issues you will need guidance on. The Roland web site has more details on the different settings than the manual does. This seems like false economy to me. Roland really should be more generous with the descriptions and details in their printed documentation. The manual is 140 pages long, but only 20 pages are in English. One drawback is the bright red LEDs that indicate selections. In a darkened room I find them glaring so much that they make it hard to read the printing next to the knobs. I have to shade the LED to read the settings. I'm tempted to go inside and change the dropping resistors to make the LEDs less bright, but I'm not sure which screws to remove and it's still brand new.

Support:
Unknown at this time.

Overall:
This ought to serve my needs for a couple of years, until some new technology produces a more powerful tool I've got to have. I don't do gigs, so my needs are modest. I'd probably buy another if it were stolen.

Feature:
You can save a lot of money by using this all in one pedal the delay alone is worth every penny and then you add the other sounds and you have yourself 100's of dollars saved.

Quality:
I have said this before in a review some place else, You could drop this from your roof and the sidewalk would crack.

Value:
Compare to other units out there the sound and the ease of use make this a winner.

Desirability:
In the sunlight or on stage with the red lights glowing its just, while im not afraid to say it Sexy I LOVE IT!

Sound:
This is the best sounding multi-effect pedal out ther plain and clear make no mistake about it this unit sounds great if you dont find this unit to make the sounds you want then you must be doing something wrong. I have a great amp a good amp and a toy and all the amps sound great when used with this pedal mess with the settings and sound is there.

Ease of Use:
Just like a stomp box adjust to your hearts content.

Support:
Boss is always ther to answer your question no matter how dumb you or I can be sometime Brain Fart, they have great information on there webb site to help you or just call.

Overall:
Buy this unit if you want great sound at a fair price dont if you have a IQ of 75 or lower.

Feature:
features? There only one problem and it's HUGE HUGE HUGE, and I am stunned Boss designed it tis way. You can save pathes, right? OK, you set a patch up, you have the normal patch set with no overdrive, you have the reverb set perfectly, and you figue well, I'll set my pedal overdrive a little hotter when it's on so that you can choose a patch, then go in to manual mode and all your patch settings will be ready to use and you can kick your overdrive, delay on, and your reverb will be set. NOPE!!! I was horrified to learn that when you kick in to manual mode, IT DOESN'T TAKE YOUR patch settings in to the manual mode so that you can kick on a boost pedal, or so your reverb and everything will stay the same as the patch so that you can avtually use the manual mode for using you overdrive or turning delay on to your orignal patch settings. When you go to manual mode after bringing up one of your presets, it automaytically switches to where the knobe ar in the front, so wherever the reverb dial is, that's what you get. INCREDIBLE oversight by Boss. They have effectively stopped me from using the patches I have setup because I can't go in to manual mode and use that patch and still kick on a bost pedal, or my reverb will be totally different. My God, Boss, Are you insane? All you had to do was make the edit patch button a foot swicth so that you could go in to edit mode so that you can still use the pedals for boost and such with you preset settings. You could have made a combination of pedals go to edit mode, you could have simply made it so that the patch settings are carried in to manual mode, because folks using manual mode could have made them a basic patch for their manual mode anyway. WOW, I am stunned how this set back effetcts my use of the pedal, just stunned. Now, I'll have to use it up on a table so that I can use my presets and then I can hit the small edit button so I can turn on a bost pedal, or use a chorus in the prest I had saved. No way can i turn that little edit buton on with my foot. You have separated the use of presets and manual mode completely by doing this. My only other option is to make presets for each change I might make to my original patch. So, I'll have to set a clean patch, then trun on an overdrive, save to the nest patch then turn on he chorus, without ddrive, save to the nextpatch, then turn on chorus and drive, save to next patch, then turn on delay and drive, save to next patch? get the pisture? See how insane that is? If you would have let me take my patch settings in to manual mode then I could set the basic patch clean and then bring it to my manual mode and turn my delay on, my boost on, my modulation on. Wow, what a terible thing to realize. This will probably cause me to send it back. I needed something with presets that I could still pull up then switch to manual mode for adding boost and such.

Quality:
Awesome quality.

Value:
Great value, but it has to do a totally basic thing like allowing you to save some presets and then still use manual mode wit that presets. Now i either have to set in on a table so I can hit the small edit button, or basicaly presets are a one trick pony when you have it on the floor. Would have been so easy to allow the user to have a way to take their preset in to the manual mode--edit button is a footswitch would have been perfect, press cobinatiuon of pedals to go to edit, make it automatically bring the patch in to manual mode, My god, I can't believe they did this.

Desirability:
I wanted it, got it, loved it untill I went in to a bad dream cause you can't use presets with this thing on the floor and still kick a boost pedal on, kick a chorus on, kick a delay on, not with your presets you can't. Every time you go to manual it switches away from your preset to whatever the dials are, no using pedals from the patch mode, uless you want to bencd down each time yoy swith to a preset (every song) and hit the little edit button, then you can use the pedals like this while keeping our original preset settings. BOSS WHY?????

Sound:
Sounds great after you mess with it. At first I didn't like the overdrive/dist effects, sounded digital, but then I realized that you don't have to use the preamp section just for going line in to a recorder. The preamp section does not change your volume output to line out as long as you are playing in front of an amp. That's great and means you can still use the amp models and you are still at stomp box efects output level for the front of your amp. Now, I can set a model and they sound great and then use the oevrdrives as dirt and they sound great. There is a huge problem for me though, which will probably have me sending it back Read on.

Ease of Use:
accept for the above, which means I'll probably send it back.

Support:
Don't need it, though I am getting ready to call Boss to complain about the manual and preset mode FOREVER being separated.

Overall:
See above fr the limitation that will probably make it usless for me.
