Even so, the ratio between these cases (where we have mostly only heard one side to the story) and the hundreds, perhaps even thousands of basses Maruszczyk / Mensinger have produced so far wouldn't worry me. It also happens that I have had 3 basses made in 6 years with no problems, including a headless.
What I am reading about the string clamp has me concerned. Have you changed the strings much on your headless? How does it work with tapewounds and flats?
I am reading about the headless system snapping G strings. I have also read cautions about the head piece potentially unraveling nylon tape windings, and flatwound windings.
While the headless design has it's appeal,....the more I read, the more gun shy I become. At least it is killing my GAS a bit.
