The features of an electric violin, being an instrument which has always been married to the forward march of technology, can be so different as to disallow the instrument to gain the accepted status of other similar electric instruments, like the electric guitar or bass. For advice on electric violin features, it is always better to hunt around and ask before deciding on which to buy.
The first source to ask about good electric violin features would be someone who has had experience in using one and who can tell the best electric violin features that you have to watch out for. Failing that, one could try looking at websites dedicated to electric fiddles, such as www.electric-violins.net. Some of these have forums where one can sign up and talk to other violin enthusiasts; perhaps the advice they seek lies here. One can also find listings and reviews of particular brands of electric violins and accessories where they can check electric violin features and compare electric violin features side-by-side, and make their purchase based from a more informed standpoint.
