Don't forget to start with the pots and caps. They control the tone nuances as much as the pickups. You'll search through a lot of pickups to find one that matches a pot that is on the wrong end of its tolerance band for you. I've fixed some guitars with just a five cent cap from 0.047uF to 0.033uF too. As for pickups, check ebay. Not all the P90s are as good but some are really surprisingly nice ... and less than $15/set. http://rover.ebay.com/rover/1/711-5...0001&campid=5338148343&icep_item=151620456535 http://rover.ebay.com/rover/1/711-5...0001&campid=5338148343&icep_item=272681543151 Sellers change frequently as they buy a bulk batch from the factory and resell so you need to look at construction details of the parts. .
