OK, I went to their website. No service centers period. I looked under support and got jerked around via a fill in the blanks waste of time. I check with the local Guitar Center. Warwick basses? Isn't that Stans basses? or some other liquored up receptionist. But don't worry their tech can handle anything. You people have never heard of Warwick Basses and yet you wish me to drop off a 6000 dollar bass in the hope that yuor guru can fix it? I'm not feeling that. I'm in North New Jersey. Does anyone know a legit Warwick service center? The last thing I want to do is get and get the bass back with an un-needed new preamp that isn't designed for this bass but he had laying around.
