It's been nearly three years since we reported a manufacturing issue that now seems to be sufficiently corrected with D string loops on the JazzMando JM11 sets. What was happening was some of these were wound too tightly on the loop, yield a circumference too small to fit on standard tailpiece tangs. In a few instances, this has affected the string's core, making it impossible to intonate correctly up the fretboard.

We were able to provide replacements for those that had D string problems, and other than a few left over from the old batch, we've not had concerns since. We did change the packaging last year, but that didn't change the string at all. They still have the same smooth comfort and playability that have made them a perpetual best selling flatwound string for the last seven years.
