Just received a One10 yesterday afternoon and used it at a bar-in-a-restaurant gig (keys-guitar-bass) last night. Obviously there are things I do not yet know about this cab since the gig calls for only modest volume level, etc., but so far my impressions are very favorable.
And like others in this thread, my first impression is about how very small it is. It's about 1/3 the size of the Big Baby II. 15 pounds, and given its size, weight and carry orientation with the handle on the side, it felt just like carrying a fishing tackle box.
I should say, the amp I used is a Aguilar Tone Hammer 350. At first, unwisely I had it up on a kind of "restaurant booth" type seating bench which had proved better than on the floor in past gigs with a different cab (SL-112). We were playing in a very cool clam-sell amphitheater type area with very limited apace under/within the shell. It seems to have a little rattle which I was able to attribute to sitting on the material and rattling against it, and also needed some amp EQ in that (undesirable) position on the seating.
I moved it to the floor, rattle was gone, a great thundercloud of tone gathered and the thunder ensued. Okay, overly hyperbolic. But, the tone was just suddenly excellent. This is in a room with challenging sound characteristics not the least of which is that visually cool clam shell backdrop. Best tone I've gotten in the place, and I played in there probably 20 or 25 times.
I did not push hard with volume, but to the extent I used it, there was plenty of volume and more, with surprisingly deep, tight bass. There is no horn in this little cab but the highs were present and, like the other Barefaced cab I have played through, has a kind of mid clarity and presence-- a clear definition of notes-- that is not a "loud mid" or honky mid tone. I kind of hate high-mid heavy sounds, and I was able to get exactly the kind of sound shaping I like, this cab does not have a characteristic sound that overwhelms what you put into it.
It gives a pretty clear, distinct, non-muddy, non-abrasive sound. I played with both a 4 and a 5 string, and was very happy with the handing of the low notes.
What remains to be seen is what she'll take in terms of sound level and pushing it a bit harder. From the sound I am hearing at these volumes, I see no indication of break-up or overtaxing on the horizon. Everything has its limits though so I will try to find out where they are without crossing the line. I'll probably bring it to a gig or two that I use a larger cab for, and just try it out for a set or something, to see. Playing with a drummer will give me some idea of its capacity, which will happen soon, but not until after the holidays.
So, based on one pass, this cab is as good as advertised. I definitely see this ias being very useful for me.
