i am using an md300b amp on an ag duo , some of the worst sounding amp i had heard on these
the guy i got it from says to get different tubes , but stock it sounds shit , its veiled , bass shy and all about midrange , rooled off on top
i am so dissapointed .its not even funny
i have an AG model 3 amp , and to my ears its far far superior
i cannot think of one person that can honestly keep a straight face and tell me it sounds good
however it looks good and seem to be totally silent on a 104 db horn
