I bought a Warwick Fortress in '95. I took it in after a year or so for a setup...the tech said he couldn't turn the truss rod?? I called Warwick and they couldn't understand...they asked me to send them the bass, which I did. They said somehow the truss rod had broken, and they replaced the neck NO QUESTIONS ASKED, all I had to pay was shipping. I thought that was great customer service.
