well...
i used to owned a mg50 , and gig with it ..(finally you will hear some positive comments for mg )
among all my amps , all the amps i have tried...from roland cube to laney tube fusion to laney hardcore max..
Marshall MG have the high freq mids to cut through (contour and mids knob) , while you are performing a solo live ...(my band has keyboards , saxophone..so it aint easy to cut )
infact , i would say , havent seen a low range amp that can cut as good as the MG ..
line6 spider 2 ...can cut pretty nicely also ..
roland cube , may sound the best , and best practice amp , and for recording..
but it is the WORST when jamming and performing live . no matter how loud you put , your sound surely kena drown , even by drums..oh yea ..i think ibanez amp is worse...
as for AD50 ..i havent gig with it before ..so ..no comments ..hehe
i will read and pay attention to this comment.
from wat u say here is that MG is the best for performing. but roland cube isnt that great for live performance. hmmmm...
