Had a '64 Gibson Melody Maker D in need of a truss adjust and none of my 5/16" sockets would fit, too thick to grasp the nut. Enter the StewMac Wrench Set. Fantastic compact set for the shop or in your guitar case. Fits like a glove in the Gibson. And the price, IMHO, isn't too over the top. Thanks again StewMac!

It doesn't fit in the bore of the neck on my es les paul.

Does what it says and does it well

Just what the Dr. ordered!

Decent enough.

Conical shaped end on these wrenches, saved the day on my vintage carvin. Just fit, facilitating critical adjustment needed.
Amen

I bought this to adjust the truss rod on a Westerly US made (in 2000) Guild Starfire IV and it fits and works perfect. It feels like great quality and durable steel. Thanks for a great replacement tool Stew Mac! Two thumps up!

I needed a thin walled 5/16" socket for old Peavey T-20 bass and this item worked perfectly on the truss rod.

This was almost perfect except that I had mill down the spiky end so that it could fit the pocket enough to actually grasp the nut and be able to slide it on. If you don't want to scrape any finish, it's best to really get it polished down after filing it. Now, not every guitar under a certain brand or the thousands of copies are the same so you may or may not have that problem.

Overall, I wish it wasn't so hard to find a nut driver wrench in this size. It's a bit on the spendy side for a little wrench that you may have to modify. Try telling a customer that if they want their own truss rod wrench that it costs $17 just to get it, and possibly more if you want to charge them to machine it. just trying to make something off it is difficult when you feel like it's already over-priced.

Overall, I am glad I found one in the correct gauge. I would just be nice if it didn't have any extra story to it beyond the ridiculous price. $9 for the wrench and around $8 to ship something so tiny. Mind you, I'm in the continental US and not in a rural area.

Peavey doesn't sell the truss rod tool anymore so I tried lots of different things to fit the truss nut and glad I finally found this. Probably works on all 1980's Peavey T-## models.
