I don't have an exotic like a Lakland,just a Carvin. However, I suddenly have the same problem.(Could be a virus being spread thru Talkbass My electronics are distorting and the signal is fading in and out. Yes, I changed the battery and still the same effect,plugged in my other bass and it was fine. Tried the Carvin again and the same result. Any thoughts. What the hell? I WILL have to send mine out. I live in a backwwods town with no hope of anyone around here benig able to repair it. Damn.Damn.Damn.
