Wurlitzer E.P Speaker shut off Switch::
This speaker shut off switch is perfect for any student model or pro model. With a student model the extra hole is already there under the wood base. In a 200 or 200A you would need to mod the case either thru the face plate or thru the side plastic cheek blocks or on the side of the case or on the rear. With a 200 or 200A you don't really need this as you can always put a dummy jack in the headphone jack to shunt the speakers. With the student models you need this though, since you do not have this option with headphone jack.
