Musically present and please upper mids is what I'm looking for, something akin to that GK-style aggression without the tweeter harshness and constant pinging. More Larry Graham, Chris Squier, John Entwistle, Geddy Lee, and not Marcus Miller or Mark King.
This is the cab for you! One thing that gets confusing on this site is that quite a few people talk about 'midrange loaded cabs' as a general class of cab. While I guess that is true in a limited sense, depending on the mid driver, these cabs all sound VERY different.
The ML112, using that wonderful Faital mid driver, and a slightly higher cross over point than, for example, the fEARful cabs, results in a totally NOT PA like response up top. The ML112 is bright, of course, meaning it has some nice presence in the upper midrange (i.e., that 'just below the tweeter' type tone), but it is very papercone sounding (versus, for example, the 18Sound mid driver crossed over low with the fEARfuls), which sounds more like the top of a PA cab (which is NOT my thing at all). When pushed up top, that mid driver can break up slightly for a very 'natural' top of the driver sound, with a bit better dispersion of the upper midrange, and of course, allowing Roger to use a more heavy duty driver to pound more in the mid bass region.
I think people call the ML112's 'bright' due to the nice 'top of the driver' type of response in the upper midrange (versus, for example, the lack of those frequencies in the Epifani line of cabs).
The top end of these cabs is the best 'grind' producer I think I've heard.... very warm, very present, but no harsh gank like in some other mid driver loaded cabs that I've played.
IMO and IME!
Edit: So, if I like it so much, why don't I have one? Well, in my detailed A/Bing of the ML112 with my Bergantino AE210 Vertical (with the smoother crossover), the overlap in tone was about 80%, and the 20% difference (a little tighter low end and a little sweeter, more extended top end with the Berg) was in the 'favoring the AE210' direction for me. I'd be darn happy with either, but already owned the Berg, and really like that form factor.
