The Bullet™ Jack Tightener works from the outside to prevent twisting and shorting the wires on the inside. Simple and inexpensive, it's a pocket-size fix for loose jacks in guitars and amps.

Tighten (or loosen) your guitar's jack in three easy steps:
  • Put the socket head over the 1/2" nut.
  • Press the rubbery Grip-Tip™ into the jack to hold it.
  • Turn the tightening handle. Easy!

Fits US-sized 1/2" inch nuts for 1/4" inch jacks.

The Bullet™ is smooth molded plastic, so it won't scratch your guitar or amp hardware.

Less than versatile

The product feels insubstantial (like many budget string winders, feels like it could snap too easily). In addition, does not work well on all amp jacks (particularly those with dome-topped nuts).

Not very happy with this

I am not quite happy with this. I was trying to use this to tighten the input jacks on my Roland JC120 amp and Hartke HA5500 Bass Amp and I cannot use this thing to get the job done! If this is advertised to be able to be used on amp jacks (apart from the strat output jacks), I suppose I can do the job with this little gadget but it failed. The plastic materials used for this seems too soft to really hold the bolt tight, or perhaps I was not well informed/instructed to use it properly? I think some more user instructions are required.

small let down

I bought three, one for each guitar case I gig with, just in case I lose one. I was let down by the build quality. The plastic isn't as hard as I'd expect it to be for its designed purpose. I was surprised at how soft the plastic was to be perfectly honest. I suppose it can serve as a "quick fix" until you can get your baby home and fixed by the proper tools. Id recommend the Jack the Gripper Hand Tool over this Bullet version.

Cool Tool

You want one of these. Turns a real PITA procedure into a 1-2-3er.

the next best thing to being there

I still like my "Jack the Gripper" best but since I'm not at both shops at the same time ...and my tools are off limits, the boys can fix one of the most common problems on electrics without involving me (-:
