As used by some of the world's premier pickup winders. Approximately six ounces. If you've got a squealing pickup you should try to properly wax pot the coil before you throw it away. Use an indirect heat source double boiler water bath to heat the wax. NEVER use a direct heat source like a stove burner. Use no more heat than it takes to maintain the wax in a fairly clear liquid state. Dip the pickup in the liquid wax for about a minute until you no longer see any air bubbles.
