boss me-50 has cosm. means it models its sound againsts its original analog pedals. so you have an analog sounding patches.
it has 3 pedals "od/dist modulation delay"
so u can have up to 3 different sounds on any point of time. alternatively you can store patches, meaning instead of bending over to adjust, u can just switch. it also has an expression pedal for wah , voice, octave adjusting.
Serves me very well and fantastic. Best Multi FX ive used ( Zoom 707II , pod xt ).
between 400 - 450 first hand. get it at 310 on soft 2nd hand
