OK, I bought these because I actually needed a single extra small capsule condenser for my home studio. I originally bought The sontronics STC-1, but I had a faulty one, and I also didn't like the general quality of that product, so I opted for a refund.
So, I'd just bought another t.bone mic, the MB75 Beta, and was AMAZED at the quality and sound, so i thought I'd take a chance on these, and hopefully get two mics for less than the price of one.
I'll try not to repeat too much what other people have said, but these mics come in a sturdy case with all the accessories you need to get them mounted and running. The mounting parts are of an acceptable quality, but they're not of the highest quality, but no problems so-far, they do their job.
The mics themselves on inspection are made very well. The switches for instance are nice and affirmative, unlike on the aforementioned sontronics. The construction in general is apparently faultless. Like the MB75 BETA, nothing to suggest anything about it is cheap.
In use they have extremely good rear and side rejection, better than my AKG C1000 (v1). So great for situations where you have an untreated room or fear of feedback. They also have more apparent volume in the channel for the same amount of gain.
Sound wise, they offer a good palette. i would say the AKG C1000 probably has more subtlety, but the SC 140 is somehow 'punchier' and more even for certain applications, if such a thing can be said. I would say that this mic is very suited to applications with complex competing frequencies, like percussion and percussive sounds like strummed guitar.
I record a lot of hurdy gurdy music, and you have in that instrument a constant battle between melody and percussion from the buzzing bridge. Very difficult to get something your happy with with printed this instrument. This mic gives a really nice directional, even response. I used this combined with a tailpiece mounted AKG C418 for a little extra 'support' the melody, and got one of the best sounding recordings I've ever achieved
With more 'common' instruments such as acoustic guitar/percussion etc. Perfectly good. Be happy to use this any time.
So I've concentrated my ratings on the mic itself and not the mounting parts as they are all extra to me. Exceptional value for money.
So now I'm thinking of more t.bone mics to play with. At this price I can afford quite a few! Probably will be now looking a the t.bone Ovid system as my old C418 was actually the weak link in the chain, by being relatively noisy compared to the SC140.
