I just want to start out saying that I have no affiliation with the products I now will praise :-)
I have for quite a while been looking for a good way to mic up my fiddle. I play kind of soft, so I have trouble with feedback or not being able to be heard. The best I tried was a borrowed DPA violin clip on mic. It was fantastic...but very expensive and unaffordable for me. Would cost more than my fiddle did.
But recently I bought a t.bone CC100 from the German company Thomann (largest online music store in Europe).
Its a copy of the DPA mics and made in China I think. But it cost 10% of the DPAs. It's probably not all the way up there (quality wise) with the DPA, but I think it's really really great none the less. I have tried it when recording.
I have also tried it live. No problems with feed and a good sound. In our band we we so surprised that we bought CC100s for the banjo and the upright bass. Worked great for those instruments as well.
The only thing I'm not thrilled about is the violin clip that was sold with the mic (as a packaged deal). It's not really tight enough, and the hard plastic makes it pick up a bit of sound from handling the fiddle. BUT luckely the CC100 fits DPAs exellent instrument clips. So I mounted it with the DPA clip (thomann.de/gb/dpa_vc_4099.htm)with great result.
