I've been really stuck on a decision for a while now between buying a Scott Cao 1713 Gibson 750/850 Series or the Fiddlerman Soloist violin. Can anyone post any pictures of the 1713 Gibson made by Scott Cao and what you like about it? Or the same with the FM Soloist violin.
Pierre is definitely the most qualified to answer this question. He's got both and he's played both and he won't steer you wrong. I've bought two fiddles from Fiddlerman and both times, I was impressed with what I got for the money I spent -- rare these days.
However, with regard to your question, I've wondered the same thing. I have seen the Scott Cao's played on youtube and they look and sound nice and just from hearing both played on videos, it sounds like a toss up. Scott Cao is a highly regarded builder, but then GCV is well respected too. So... No help there.
I own a Soloist and I can tell you first hand that it's a really nice fiddle and definitely worth the price. I've had mine for a little over a year and I don't think I'll ever need to buy another -- barring some sort of violin tragedy. Whichever way you decide to go, I'm sure you'll be happy player and proud of your instrument.
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. ~Herm Albright
