One of them was mine and it just sold. It took a while to shift and I lost a little money. I hardly used it as I discovered that my D7000s sounded better through the EF5. The Concerto is a very dry sounding amp, but then I came to realize I like the lush warmth of tubes, or at least hybrids. I would recommend to anyone who's thinking about getting one to try a demo unit if you can (local meetup, canjam, etc.) "Buy to try" seems to create a diminishing return.
