Ok, im having majormajor problems with my Tobias. Something is pretty damn wrong. When i plug it in to my amp (im using the practice amp now, the other is at guitarists house), it crackles...nonstop. It phases in and out or sound (like, youll hear the string, and then you wont), and when you can hear the sound, it clips like hell. I learned recently that THIS caused the problem with my Fender amp (and, of course, transferred the problem to it, causing me to have to get it fixed). Its really bad...and its like killing the amps. Ive checked the cavity, no wires exposed to touching, and its fully shielded. Ive had the jack checked, and its perfect. Is it my pickup? Its a single Bartolini quad-coil...i think it might be. And thats bad, because its like a $300 replacement. Help! If you need to explain more what it does, i will. Buts its like killing the amps, because it causes the amps to clip no matter what instrument im using for like 10 minutes after i use the Tobias, and then it wont. Help!
