I'm trading off my acoustic guitar (permanent shoulder issues aggravated by the arm position for playing acoustic) - I've been offered a trade for a 2003-2004 American Telecaster. Haven't seen it in person yet and will look for the usual issues, but it looks like the pickups have been traded out for EMGs. the owner doesn't know much about the guitar and can't find any batteries. Does EMG make passive pickups for Teles? if not, where would the battery be? (There's no door on the back .) Any other issues to look out for? I read somewhere that you may have to route out a Tele a bit to fit them in. Any reviews on Teles with EMGs? I'm not a huge fan of the EMGs in my Synapse, but those are humbuckers.
