Has anyone here tried a Super Compact with an upright bass? I'm thinking of adding a SC or a One10 to my BB2 to make a stacking option and to use for upright gigs, or low volume electric gigs.
I am not an upright player except in my basement for now, but I've heard from a number of upright players who like the Super Midget, so maybe that's something to consider.
@LowNote has a One10, an SM, AND a BB2 and uses all 3 with his upright, IIRC, so he'd be a great person to ask. Also IIRC, he tends to set the SM or BB2 horn very low to off, to avoid string noise. As such, it's hard to imagine a SC NOT being decent for URB.
However-- IMO, between the SC, SM, and One10, the SM would give you a better stack option (for EB use); and the SM is an excellent little cab for stand-alone use depending on gig size. I use it a lot, and will use it tonight.
I don't think Alex particularly recommends using the no-horn SC with a BB2 or SM which both have the horn; nor does he recommend mixing the 10's and 12's since they have such different tonal goals. There are a few here who disagee with this, and like the SM + One10... but I am not at all sure mixing the drivers and inherent tone of a 12" BB2 and a10" One10 is ideal. I tired it once combining SM with One10... it was certainly serviceable, but I didn't think it was super great sounding, but I'll admit that the terrible sounding room probably had something to do with that.
An SM with the horn low to off would IMO give you pretty much everything a SC would, except with slightly less bottom end maybe, due to box size (but SM bottom is fully adequate). And it pairs with the BB2 well in a stack, more so than an SC I believe (though I don't have an SC). TheOne10, by all reports, works well with URB; an is a very handy stand-alone tool for small gigs with EB too, I find. But maybe not the best candidate for stacking with a BB2.
Bottom line, I'd ask LowNote about his Barefaced cab/URB opinions. Here's a quick link to a thread where the SM, One10, and BB2 are discussed by him and others with respect to upright bass. Good luck!
