I've only had my Bon Cajun a couple of months, and haven't had my Ariette out of the case since my beautiful Bon C arrived, but this discussion got me interested in a side by side comparison. The Ariette really doesn't sound at all bad. Tuned MUCH wetter, so certainly not as authentic sounding, but really does sound pretty nice. I kinda like the tremolo you get from the wet tuning. The main difference is the bellows are obviously much cheaper and are very stiff in comparison so Larry's so it is much less responsive and harder to play. The buttons are quite a bit "clunkier" too. Overall harder to play fast button and bellows changes. Of course, the wood is really cheap, and construction shoddy, so visually the master craftsman's box wins hands down. But again, the sound really is pretty decent, and for someone wanting an el cheapo to try it out and learn the basics it really is a hell of a bargain. I'm going to keep my Ariette intact until I send my Bon C to Larry for tuning, but once I get the master's box back, the Ariette is coming apart to see if I am any good at tuning.
Marc Savoy's instructions on how to tune an accordion was completely fascinating. Previously I had no idea how they were tuned. Really quite remarkable.
