The packaging is exceptional and well protected. Upon opening the strings, they have a great feel to them. I was super excited to put them on and try them.
Issue number one. They are a heavy string and I had to fully tighten my truss rod against their pull. I did not like this so much. The action changed drastically from my previous strings which were D'Addarios.
Issue number two. After the adjustments were made, the tuning was very difficult.
Issue three. After getting the guitar as close as possible to being in tune, after a few minutes of playing and tuning the high A string, it broke. Now, I've broken a few high G strings before, but never an A string. I removed the strings and restrung the guitar with Pyramids. MUCH BETTER. I really don't like these strings, however, I use Ernie Balls on my E guitar with no problems.
Problem four...they sound terrible
The plus is the feel. They felt great. Very smooth and responsive, however, they are very stiff.
