I am new to Telecasters; have only been playing one for about a month. I finally popped on an ashtray bridge cover on my Tele and I think I hear a difference in tone when I play through my bridge or neck/bridge pickup. It appears to me to be BETTER! Can this little piece that most of you guys just toss in your case actually affect a Telecaster's tone? Is something going on above that bridge pickup but trapped by the ashtray that can affect the tone?
