Can't find a Peavey T-40 truss rod wrench

[Peeved T-40]

I know this has been asked about before but every thread i find about it is sending me places that don't seem to have one anymore.

I've looked on the peavey site and didn't see one. I've looked on stewmac. People have said it's the same wrench Gibson uses but i can't find one on their site either...

I'm lost and really need one. My neck is a banana right now

If it’s 5/16”, and it’s been a while since I’ve worked on a Peavey so I’m not 100% but I think it is, Allparts seems to have them.

LT-4216 5/16 in. Box Wrench

If the neck is that bad be sure to remove the string tension and “help” the neck into position by hand or, if needed, clamps before you start cranking on the truss rod.

It needs to be a thin wall socket like in this listing:

Groovetech by Cruz Tools is your best bet. Maybe $15 to $20.

Hex keys fit the saddle and knob grub screws, 1 Philips head fits the neck screws, the other fits intonation machine screws. Leaves the 5/16th socket.

Here's an action shot of mine.

Like I said, been a while but I thought I remember using that same wrench on a friend’s T-40 with no issues. If not, I don’t know what wrench I used to set it up...

I use a gibson box wrench for mine and it works beautifully. Much easier to find.

 

[NOVAX]

Gibson case candy wrench. Ditto.

I used a Gibson wrench on mine.

It takes a nut driver right? My PRS is a 5/16 drive. Probably something similar. You can actually use a socket if you don't have a driver. I have before. Just gotta find one that fits in the hole.


Edit: get a gibson wrench. It seems everybody else uses one.

The opening is too narrow to use a normal socket.

I got one in on my kestrel. No problem. Don't have a t-40, but he could probably find one that fits.

Not saying a socket from somewhere won't work, but I tried several brands, and the walls are simply too thick to fit into the small route area on usa peavey instruments. Plus you really don't want to force something into that spot, as the necks are two piece laminates prone to splitting under force.

Just get the right tool for the job instead of searching for something that is likely too big. A gibson truss wrench is very cheap and readily available.

You can easily reduce the outside diameter of a cheap socket using a bench grinder.

I use this one...

I don't know if Peavey changed the rod nut on these basses but I remember mine not accepting a Gibson wrench and I did eventually find one that did work. I don't know the size off hand but if its 5/16ths then go for it.

 

[NOVAX]

Or, find a nutdriver that fits and then grind down it's external diameter until that fits.

Just wanted to mention not all of the generic truss rod tools are the same. I bought a similar one also from Amazon a while back for my Peavey Fury and the walls were too thick to fit into the cavity on that one. If this one is thinner, that's good to know. I also heard the one from Stewmac worked for many folks, maybe because it has thinner walls too I'm assuming.
As recommended by someone above, if you have one, you can use a bench grinder to reduce the diameter of the tool if you need to.

Reading the comments section, it should work as it looks like someone with a T40 used it and it fit into that hole.
