I orderd some flats from "Bass Strings Online" for my SS Gibson SG. Their was a mix up and the strings did not get shipped. I called Jason to remind him of my order. I received the strings a few days later. Jason emailed me that the shipping and cost of strings were on him as he said he made a mistake. Wow, I never expected a full refund! I have 7 basses and will buy all my strings from "Bass Strings Online" in the future.
