oh i see..... how do you know if the batteries are dead
You turn your amp on and you guitar won't get any noise from ther guitar period. My band teacher had a $2000 dollar bass that he thought was broken until he remembered he had active pickups.
pickups stop working to an extremely obvious magnitude
