1/4" Jack - Mono, PC Mount, for Fender® Amps '88 - '99

Question:
Replacing an input jack (J1) on a Fender Super 112 combo. I removed the bad jack and noticed there are only 3 pins. The J1 PCB footprint has 4 thru holes. Does this 4 pin replacement jack use all 4 pins or should I clip off pin 6? Thanks for your time!
