i posted a few issues with my cc121 in the hardware forum, months ago, nothing but crickets …anyone know how to go about a warranty swap with steinberg for a new replacement unit ? less than a year old. Purchased from guitar center.
thx
Have you tried contacting Guitar Center? They are pretty good at helping their customers. You might get a quick swap there.
If they can’t assist…
I would think you would put in a support ticket. It is located in the “My Support” section of your “MySteinberg” account. Below is what is found on the Steinberg website for US purchases.
