Just a heads up to the players of these. Whether it's a bass or guitar with active electronics. My friend just scored a deal on a Stingray 4 that was dead in the water for 170$. Was told by the stores tech, that the electronics were shot and needed replaced, but cant find them. Sooooo... here's the trick. EB is the ONLY company that uses a diode in the battery compartment. Cost was 1.50$ for a simple trick. He was so thrilled that I got it fixed. Make sure the person knows how to troubleshoot. They're is a big difference between a player that "techs", and a tech that "plays".
