well here's my review of ME-70
Easy of Use: 9
Well...even without reading a manual, as long as your hands are always itching on those knobs, you can the tone that you always wanted easily. Also with the EZ function...you can bring up factory preset tones easily as much as well tweeking them fast. Although you don't visually see the parameters when you save a patch, you can see the value by holding down the edit button while moving any knob. Well the negative side is, there is no way to go into manual/stompbox mode within a given patch! Well who cares? You can setup your own effects in a way you will stand off. You can also work your way out better in the ME-70 if you have a footswitch.
Tweak tweak tweak!
Sound Quality: 9
You know what we're talking about here. It's a BOSS! and when you hear it you'll say HEY ITS A BOSS!
I like the COSM preamps and also the lovable EQ!
Harmonist seems fine but I prefer a more intelligent setup. Other Modulations are cool. Chorus is somewhat limited but it still fits my style. Delays are super cool and you can do a dual delay effects! Overdrives and distortions are great especially when placed in tube amps or tube ODs. Wah is standard but I prefer a more flexible WAH. Noise gate is good and can be setup individually per patch. Reverb is divided only into two somewhat still limited but it fits my style evenly. Some say that the volume pedal is very sensitive. About that, you can read the manual. There's a portion there on how to adjust the sensitivity of the pedal. You can even make a violin or piano-like sound with this ME just tweak it out!
Appearance: 10
Cool knobs...cool paint...cool lights...cool design! Although the paint chips of easily when you drop it...ooopppsss...
Reliablity: 10
IT'S METAL..IT'S A TANK...IT'S BOSS...again ...IT'S METAL..IT'S A TANK...IT'S BOSS..
Overall: 10
If you don't have the money for GT-10...this one's for you...of course...it's much smaller, lighter, easier to carry and can be easily chained to pedals or effects alike..
