I had and sometimes gigged the 115 for a little bit under 2 years and liked it a lot. I was never in it for the Toneprints, but there are fx and more “utility” ones (compressors and drive). I didn't really need or especially want a combo, but kind of ended up with it. For the time I had it, I found it to be completely capable and I enjoyed the convenience of running with a combo. The 112 is the only one in the line that I didn’t ever get my hands on, but from my other experiences and what I’ve heard and read, I’d suspect it has some good and bad elements that will come down subjectivity. Bottom lining it; a nice, middle of the road combo in it’s class, with some features that have the potential to be solidly beneficial (i.e., if they’re ones that you use).
I came away with the impression that the cabinets on these (possibly to a greater extent than some others) can have an inherent sound that can be a real challenge to move away from. That’s fine if it’s something you like and, obviously, not so much if you want to alter that part of the sound. One of my few complaints in the 115 was that I found a slightly nasal sound that seemed inherent to the cabinet…but what I label “slightly nasal” some others call “open” or "vintage" (go figure). Anyway, it sat well in the mix, and that aspect of it was only something that my ear zeroed in on with bedroom use. In that bedroom/practice setting, the 210 sounded better to me in that one regard.
It's neither here nor there, but I also found it had a nearly magical (obviously an exaggeration, ha) interaction with the amp/preamp sims on the Zoom B3, which seemed counter-intuitive…but there it was.
Another complaint was that I felt it carried heavier than it was. I think that was because of the dimensions and handle placement (combined with my height). But the 112 is smaller, so that was specific to the 115/210, and a single top handle is probably fine.
The last complaint was that the tolex used picks up scrapes and possibly even tears more easily than others (overly soft).
It did what I asked and expected of it as a 115 combo. I never experienced “farting”, found it plenty loud, and have to say that criticism of wattage in the context of the BG/BH 250, 550, 800 is simply a misunderstanding and misapplication of criticisms of TCEs Active Power Management (which were usually oversimplification/misunderstanding of that).
