Is there any reason why I shouldn't fasten the pickup to the body of the bass with screws? I was just thinking there might be some tiny amount of vibrations from the body of the bass that might somehow conduct (mechanically) into the pickup-- affecting the relative position of the vibrating string and the pickup. I'm not talking about microphonics (like from an unpotted pickup). I just mean that the pickup is not entirely stationary while it's reading the string. And is the tiny movement of the pickup substantial enough to affect tone (especially of the body's vibration has a weird phase-relationship with the string)?
