Nope. Was just playing my HB II this am and it doesn't lack any frequency response. It's got a bit more "air" to it, which I know is a cliche for describing guitars with space inside them, but I absolutely find it to be true. It's not as "warm" as my 594 even though it has the same pickups, but to me that's more about the scale length and solid body construction than it is materials. And at the end of the day, it's harder to put clarity and brightness into a guitar that doesn't have it than to pull it out of a guitar that does.
