Theres a Strummer at my local dealer, but I've never played it, so I can't speak to any characteristics. This hum you may hear may or may not be a problem.
If you find the diagnosis difficult to do (or fix) yourself bring it back to the dealer where you bought it, or a a fender authorized dealer if you're the original owner and it's been less than a year since purchase. Otherwise you'll likely pay a fee for diagnosic/repair if the warranty is out.
