I just became acquainted with a neighbor who owns a five string Warwick bass. Knowing that I build partscasters, he asked me if I could do a setup for him. I told him I'm not sure if I'm qualified, but I'm interested to know if there are any particular issues in working with the brand. (I've never even seen a Warwick). It sounds as if the neck is somewhat bowed and the action's high. Do they use a standard truss rod arrangement or are there special things are person would need to know before doing something like this?
