My Spector's bridge pickup sounds very "farty" ....like a blown speaker turned to 11. The two pickups nearer the neck are fine. Do you guys think I should try and have it repaired? There is only one place in town that could do it and they are not authorized or anything. I guess my other option would be to replace them. Suggestions? I have been getting by with just turning the bridge pickup volume really low. But Im ready to get this bass back in fighting condition.
