Then like I said, if you need things like a dedicated tweeter amp, a biamp crossover or any of the things the GK has that the MB doesn't AND don't need any of the benefits the MB brings to the table, you're already set. The LMII is easily as loud if not louder IME.
Looking at tone shaping capabilities on it's own has never made sense to me. It's nice to have the abilty to tweak the tone to get a tone you like but IMO it's far nicer to not HAVE to
With all the info available on the LMII it should be pretty obvious it doesn't have ALL of the features of the GK.
