simply put: mark bass mini cmd 121p or gallien krueger mb112? clearly, the mark bass is going to be more versatile, but is it worth the extra dollars? In Australia, where I live, there is about $1000 between the two. I play in a multi genre band that plays quite loud, but in small venues. The Mark Bass is going to be louder but would the GK do the job? people with amp knowledge, enlighten me. thanks.
