Hey My question relates to piezo cable under saddle pickup for accoustic guitars. They change the guitar's sound into electrical energy. They work almost like a microphone. But these cables are bendable, would that mean bending them can cause an electrical impulse along Becasue they are up of piezo electric materials? But if this is true, when a guitar player is playing, they hit the guitar, so the cable vibrates too; so wouldn't the impulses from sound and the vibration be picked up by the piezo cable, so the sound heard from the loud speaker is no longer clear?
