Ummmmmm, I'd drop that guitar store.......I don't have my guit tools in front of me, but let it be said, it's a standard metric allen wrench, NOT hard to find AT ALL .......I bought a set for working on my bicycle years back (all that stuff's metric...) and I'm guessing it's anywhere from 2mm to 5 mm for the Epi LP tr (at least it worked on my '07) ....off the top of my head, I'm thinking towards the smaller end of the range - am posting from a relative's comp. Good luck, and just go to a hardware store and buy a few small metric allen wrenches - always good to have extra tools on hand...or wait until someone posts the exact size you need=d> Quote Link to comment Share on other sites More sharing options...
copper1281734000 Posted May 10, 2008 Share Posted May 10, 2008 A very handy tool set to have is an allen wrench set. You'll eventually need some of them later, but the kit has them in lots of various sizes. I found the size I need for my guitar in minutes. It's always good to have a set of allen wrenches, and you can find them at hardware stores, like home depot, or someplace like that. I don't know how much they cost, but they can't be very expensive. I'm going to guess (not sure) under $25. Good Luck! Quote Link to comment Share on other sites More sharing options...
bluesstringer Posted May 10, 2008 Share Posted May 10, 2008 If you plan to own more guitars ever any USA models, I would suggest getting a set of each, metric and standard. You should be able to get one of each for less than $25 for both. Good investment tool wise. You sometimes will run into guitars that have funky setups that will require you to get creative but under normal circumstances, Normal allens in metric and standard will hold you. Ovation acoutics come to mind as the truss adjuster is set pretty far from the soundhole, at least in the older USA models. Good luck !

RotcanX Posted May 10, 2008 Share Posted May 10, 2008 Yeah just be glad it's not Armstrong Whitworth size. You should be looking for a 4mm Hex key. Best is to get a long T-handle version. Quote Link to comment Share on other sites More sharing options...
dubstar Posted March 16, 2012 Share Posted March 16, 2012 epiphone sheraton II LH apparently 2008 anyone know what size allen wrench to adjust the truss rod? apparently, I've never adjusted my casino or joe pass after they were set up because I have no wrench for them (assuming they have the same size truss rod) and my elitist LP has a completely different type of wrench...the ones I use for my acoustics (epiphone and yamaha) are too large... thanks (searched but could not find an answer that clarifies what size I need) Quote Link to comment Share on other sites More sharing options...

brad1 Posted March 16, 2012 Share Posted March 16, 2012 Well, like as previously answered, most people just get a set of allen wrenches. That's what I have. I have no idea what the sizes actually are for any of my guitars. But I do know I have an allen wrench that will fit every truss rod. I suggest you go out and buy a set. They are very useful for a lot of things. And they are relatively cheap. Quote Link to comment Share on other sites More sharing options...

ralphnavarretta Posted May 8, 2020 Share Posted May 8, 2020 (edited) From from doing my research I guess 5/16 would be the measurement that you're looking for for the trus rod for Epiphone Les Paul.

Big eddie Posted September 3, 2021 Share Posted September 3, 2021 There is no thrust rod adjustment nut on my Epiphone LP 100 I just bought from a guy. It looks like it's been stripped. Allen wrench has nothing to fit into. Can someone advise me. Quote Link to comment Share on other sites More sharing options...

It looks like it's been stripped. Allen wrench has nothing to fit into. Can someone advise me. It should be a 4mm hex wrench. As they get older it can be difficult to get the wrench to seat properly, sometimes the short end of the L shaped wrench will not fit all of the way in, so try the long end making double sure it seats properly. If it still won't seat, try making a tapered hex wrench by taking a slightly larger one and file down each of the flats on the long ending working it in carefully. Epiphone Truss Rods are a one piece rod threaded on one end close to the neck pickup and 4mm socket at the headstock end. If you can't make it work, you may need to get a new aftermarket neck..

Harpdog Posted May 10, 2022 Share Posted May 10, 2022 (edited) During the mid-90s ('93 t0 96'?) Korean-made Epiphone Les Paul guitars used a Hex nut on the truss rod, not an Allen nut. It is smaller than the Gibson ones and I believe it is metric (probably 7mm). The cavity is very narrow and you will need a proper thin-walled socket angled wrench (90 degree ) to make the truss rod adjustment without risking damage to the guitar - a standard 7mm socket will not squeeze in there. The necks on these models at the headstock are very thin. I have seen some 90 degree socket wrenches with a very long socket, but these will probably not be ideal because the hex nut on the Epiphone is quite long (the nut fills a lot of the cavity) and it may be difficult to get a purchase on the end of the hex nut. If possible get a short, thin-walled angled socket wrench instead. Burring this nut will create a nightmare for you, so it is best to get the right tool before attempting the adjustment. I hope this helps others in future. ** A tool similar to the one in the link below is what you need, though I can't confirm the exact size you need. It is probably 7mm, possibly 8mm. Other Korean-made guitars (Ibanez, Jackson, Charvel) used a 7mm Hex nut, so maybe that's a clue?Truss-Rod-Wrench-7mm Edited May 10, 2022 by Harpdog Quote Link to comment Share on other sites More sharing options...
Larsongs Posted May 10, 2022 Share Posted May 10, 2022 This usually comes with Gibsons.. It is a handy little Tool to keep in the Case.. https://www.gibson.com/en-US/Gear/Cleaning-and-Care/ATMT-01/default Quote Link to comment Share on other sites More sharing options...
Pinch Posted May 31, 2022 Share Posted May 31, 2022 Always use the long end. The short end is too short. You damage the nut. Or risk to. Best Epi tip I ever got. Should be a sticky. 1 Quote Link to comment Share on other sites More sharing options...

Knowing the general shape of a Hex-Wrench you can see that it had to go in really far to seat properly. 1 Quote Link to comment Share on other sites More sharing options...

It was someone on here who gave me the tip, can't remember who it was, but it's advice that should come with every Epiphone. 1 Quote Link to comment Share on other sites More sharing options...
