a while ago i realized that there was alot of buzz from the tone control. i toook off the strings and put it away for awhile. when i set it up again and started playing the buzz was all gone. the buzz came back. i took off the strings again. put it in storage for a few days. put the strongs back on. and guess what? all the buzz is gone. i love no buzz. no buzz = good. does anyone know the cause of this?
