 They begin with a stock, but often rather crude (but usually playable) Wishbass and modify according to their own requirements.Typically this involves refinishing Steve's minimal finish ("just enough lacquer to keep the beer from soaking through") with many coats of TruOil or the like, replacing the aluminum cavity covers with wood ones that match or complement the natural woods of the bass and even reshaping the body and/or headstock.Minimal electronics are expanded with stacked pots, varitones, pre-amps or by changing or adding pickups.
