Jack The Gripper

About This Item

Ingenious! Holds the jack steady so you can tighten/loosen the nut without disassembling your instrument or amp.

A loose nut on a 1/4" jack is trouble. It's no fun to watch the jack disappear into your guitar or amp as the nut falls off, or to break a solder connection when you tighten the nut and the jack turns with it.

Designed by veteran repairman Frank Ford, Jack The Gripper is a smart tool that can save you a lot of time and work. Insert it into the jack, and the knurled cam locks in either direction, to hold the jack firmly while you tighten or loosen the nut.

Recessed jack? No problem—the tool also includes a clever adapter for use with your 3/8" square drive socket.

Instructions included.

Thank you Frank Ford.

What a wonderfully fertile mind to come up with this critter. Thank you, Frank.


A Great Time Saver

I read many of the reviews before I purchased this tool. Like one of the reviews, sure enough I was playing around and inadvertantly loosened the jack on one of my guitars! Tightened it back up with no problems. It worked flawlessly on an end pin jack on an acoustic I was fixing. It also was the only way I could tighten up a cheap jack that was just spinning with all my other wrenches. The only draw back - it's not a cheap. However I cannot deny, it works great!


Love the name

There is a bit of play in the cam before it engages. This is not an issue . Just turn opposite the way you tighten, and it works great.
