Sound — 8
There are 11 types of delay, 22 distortion/Overdrive types, 11 modulations, and 4 types of reverb, plus an expression pedal with 6 types of effects(volume, wah, resonance, voice, ring mod, +1 octave, and -1 octave). I love the Distortion/Overdrives. They are based on other pedals such as the MT-2, DS-1, the Tube Screamer, Big Muff, and 18 more. The modulations are great too. There's rotary, harmonist, chorus, phaser, tremolo, pan, vibrato, uni-V, and flanger. One of the only things I don't like about the effects is the Wah. It's not deep enough for me, but it might be just fine for you. One thing I love about the ME-50 is that it has a "Tone Modifier". I love this thing. You can change your tone to "tight, mild, presence, fat, enhance, S-H (single pickup to humbucker), H-S (humbucker to single pickup), H-HF, hollow, and acoustic.
Overall Impression — 9
I play all kinds of music, rock, ska, blues, ect., and it is perfect for all of them. I can get a great crunchy distortion for rock, a clean tenory sound for ska, and a smooth, creamy Overdrive for the blues. If I lost this one, I would definately buy another one. I love the effects, the distorion/overdrive, delay, everything about it. The only things I don't like about it is the wah is not as deep as I had wished, the Noise Suppressor is pretty brutal to your tone if you have it to high, and that Boss doesn't include a footswitch or an ac adapter. But all in all, I suggest you buy the ME-50 if you're are looking for a multi-effect pedal.
Reliability & Durability — 10
This is a Boss we're talking about. You couldn't hurt it if you tried. Solid as a rock. I would, and I have, definately use it at a gig without a backup. It does get sort of annoying to be putting all your weight on the expression pedal every time you turn it on and off though.
Ease of Use — 9
It's very simple to use. There are no menus, you just Pick the effect you want and set the settings. There are 30 preset patches that you can change to your likings or keep how they are. It's just like a chain of indivdual Boss stompboxes. To edit, all you do is find the patch you want to edit, press the "write" button, fix all the settings like you want them, and press the "write" button again. It's that easy.
