Hi, I'm the owner. Here's what I had in mind when I bought it, new, from the builder. I've been playing string chamber music all my life, as a violist. This 5-string instrument has the body of a viola, therefore is not too hard for a violist to learn to play-- as opposed to a violin, which just feels tiny. I was looking forward to using it to play the same string chamber literature, but this time as second fiddle-- for a different perspective on the inside workings of the music. It was (and I think still is!) a noble project, but it hasn't materialized as I would have hoped, which is why I'm ready to sell the instrument.
