I received my Music Man Sterling SUB Ray 4 today and it worked fine for about 10 minutes and then the sound just stopped working. I figured the battery just died so i bought a new one but it still does not work. There is some sound produced when i fret the E string really hard but the signal is weak and cuts out quickly. This even works when i take out the battery completely. -Nothing wrong with the cable or preamp, my strat works fine using it. -When i put in the new battery for the first time it got really hot, i don't know if this is normal or not.
