    EMG's have an internal opamp that is usually bulletproof, but can fail. If you have a spare 1/4 inch jack, hardwire the pickup to it, plug in a cable (a good one!) and see if you get a strong signal. A luthier would put it on a meter to see if it was getting good signal, but in lieu of the meter, that should work.

    Best of luck my friend!
