The Warmoth Double Truss Rod & Side Adjustment Mechanism Explained

Aaron at Warmoth explains double truss rods, and how the Warmoth Side Adjustment Mechanism works. The Side Adjustment Mechanism is standard on most Right-Handed, Modern Construction necks. Visit our website for more details: www.warmoth.com...

[@jean-francoisremillard9513]

This is by far the best truss rod mechanism explanation I have ever seen (side mechanism or not). Great video!

[@TheZooman22]

That's a very nice feature. I have one on a Warmoth Tele neck and it makes adjusting the neck very easy, so precise adjustments are possible. I wish more things in my life had a side adjustment mechanism.

[@lungha9827]

You don’t see the big manufacturers of guitars explaining any of this like Warmoth…Much appreciated 👍🏼

[@michaelarthurmusic307]

I have owned a Warmoth guitar with one of these truss rods for about 10 years and have only had to adjust it once, unlike some of my other (high end) guitars that need adjusting about twice a year on average. Thanks Warmoth!

[@j_freed]

They make really good stable necks even if you have the Vintage style with single adjustment at the heel. I think a little more pride and care goes in than with Fender USA necks and bodies.

[@alexcorona]

I've had my les paul for 12 years, only needed to adjust rod once...

[@snow_monkey]

@@alexcorona I only adjusted mine once, that's why my guitar plays like shit

[@andythrall7552]

Excellent explanation and demonstration. This presentation left nothing unanswered. Thank you so much Warmoth!

[@ralex3697]

This man is so incredibly articulate

[@baalzephon849]

Genius! Love the innovation. This saves so much time by not having to remove the neck every time a truss-rod adjustment is required.

[@j_freed]

Plus it being a fine adjustment, and plus it being adjustable under string tension… I’m less afraid of these things now, even though I’m totally fine with the simpler Vintage design the company also make… my Warmoth neck just never moves! (And this despite having the neck back lacquer sanded off and just oil and wax applied… that’s a good chunk of maple right there.)

[@noahbart1693]

why are these people so ingenious???? this is the best idea ive ever seen for a neck

[@robertbuilder8001]

My Strat neck arrived (in the UK) from Warmoth this week. It is so beautiful my wife keeps picking it up to marvel at it's loveliness lol :-)

[@germancarluv]

Thanks for the lowdown. Watching this video five years later. Finally Understand how the side thing works.

[@valentino3191]

This is by far the best design I’ve ever used. I’ve build a dozen guitars with your modern necks and I joke that the torsion rods on them are “set and forget.” Very mechanically stable.

[@rrguitar1]

Awesome tutorial! Well explained, enjoyed this one, thank you !!!

[@OtherTheDave]

Oh, so that’s how those work! I hadn’t realized there were two adjustment points and had figured there were some bevel gears in there or something. Neat!

[@johnsanchez8612]

All my necks are warmoth pro necks with the side adjust, I love it. Anyone saying that they "rob tone" wouldn't know tone if it smacked them in the face because chances are they are running 99 effects on their digital modeling amp computer software (to hide their screw ups). why can't anyone play with a simple jack cord straight into a Marshall anymore??? That's tone!!!!!

[@evilcowboy]

Lol I play with the simplest setup I can, I have always hated too much going on as far as effects go. I have some stuff that sit on a shelf with zero use (wah pedal, effect processor) both collect dust. I rely on pickup selection, a pedal I built for distortion (freidman-BEOD circuit with modifications to the diodes and caps used to soften the 4 gain stages in the circuit with a true bypass to get to the actual sound of my clean channel) and a Blackstar tube amp on clean with everything zeroed. It was the simplest setup I could do and get tones from the 50's all the way to now. Sometimes I will use the boost on the amp. The pickups has always been where I adjust tone and sometimes the electronics of the guitar itself so it causes me to have 2 guitars with actives from both Seymour Duncan and EMG but I got a strat with vintage noiseless in them (still can't get passed the 60HZ hum) and a couple of odd passives in a couple of odd guitars. I still feel the tonal quality of a guitar is found in the instrument and how well it is built and how well it is tailored to the person using it. Nuno Bettencourt is a prime example of a person who tailored their guitar from parts to himself. I am with you I do not consider a computer modeler an amp, it is a virtual practice amp and should always be treated as such. It can produce clean sounds and some are unique enough I actually like them but it still does not compare to the sound obtained by an actual amp guitar and a good player. There is no way that tiny thing that uses a brass containment block (which should be tonally ideal) robs tone, if a person says it does they have sloppy playing. But then again I am a person who finds guitarists like Slash or David Gilmore are great guitarists, not because of technical ability but because they play the shit out of their guitars.

[@2204JCM]

Why? Because you actually have to be able to play...

[@larrysentelle1244]

You've just described my favorite guitar tone; Guitar/Mogami Gold Cable into 2203 Marshall...COOKED! Some kid asked me how I got my tone after a show once, I handed him a guitar cable, and laughed, he was amazed.

[@hawkfan1212]

Geez! With all the great, informative (and addictive) videos you have, when do I even find time to practice!?! 😁 Keep up the good work!

[@woodygranger2126]

I've got a replacement strat neck like this one from Warmouth in 2011. It is the best strat neck I have ever played, IMHO. I did fret leveling and recrowning myself to my preferences with a bone nut from scratch. The best purchase I have ever made for a guitar part. Now, I am considering a complete warmouth Telecaster "build" to my exact preferences.

[@billnu]

Love my Warmoth neck. Beautiful craftsmanship, exactly how I wanted it.

[@drkoontz]

Great video , the cutaway helps in seeing how it all works!

[@PK08-86]

This is such a simple, genius design

[@arnieus866]

Perfect explanation. Even I could understand it. I have a wide-nut, ebony Warmoth neck on a strat. It is my all time favorite solid body.

[@schenkerrothmoore]

This is a wonderful explanation. Thank You Aaron and Warmoth!

[@indyvin]

Very well presented. Warmoth is a class act.

[@SrSagittarius]

The definitive explanation. Thanks so much.

[@Col_MULLY]

Aaron, I'd love to see a tutorial on what your instructions say when you receive your neck with the double truss rod. It explains how to set the truss rod. I'll be honest, I never could figure out what the hell that meant so I just left it alone. Luckily none of my Warmoth guitars have needed adjusting, because I didn't set anything, I just took it out of the box and put it on the guitar. A detailed tutorial on that one would be VERY helpful.

[@kerigregory7664]

Realy?

[@lone-wolf-1]

Thank you for explaining me the mystique of the trussrod!🙏🏼👍🏼 Heard the first time now about the side adjustment. Cool thing

[@adakhochalai]

Very clear explanation now I understand how a truss rod works

[@TomGlander]

A most excellent presentation and company!

[@timothycormier3494]

Straight and to the point. No pun intended. Thanks man

[@TruthSurge]

OH! wow, now I get it. It's really analogous to the fine tuners of a FLoyd Rose system. Instead of taking the guitar neck off each time to adjust you can just get it close with the main one and then use the side one to fine tune it after you get the guitar all back together and tuned up. More of a time saver I guess.

[@relevation0]

@Billie Goes get a life loser

[@noamaster3898]

TruthSurge! Love your "Excavating..." series.

[@j_freed]

Plus you’re doing the fine adjustment under string tension, and can tweak the neck if seasonal temperatures and humidity cause slight changes.

[@fenderbender3664]

Bought one recently just like you showed as your example neck. Had no clue what that side adjust was but now it all makes good sense thanks for the video! Off to mount up! Blues On!!! :)

[@thepiperofsimms9974]

[@GeorgeCress]

Warmoth is the best, I have a Warmoth pro maple birdseye neck with side adjustment, it's incredibly stable and feels great! I wouldn't want any other neck ever!

[@TheShrededward]

The bullet truss rod system would seem to eliminate the need for a micro adjustment since it seems to be a workaround to having to take the neck off to adjust the trussrod. So why not go with that/ Is it the mass taken from the base of the neck, rather than closer to the headstock where most people play?

[@PelicanIslandLabs]

Thanks for the informative video. Just a note: Those "welds" on the end of the double truss rod appear to be "brazed joints" which technically isn't a welding process as defined by the AWS (American Welding Society.)

[@anth-ny]

[@yorganyog]

[@johnpeters4787]

Very Cool Necks I own 3... The Only thing That wasn't mentioned is the Side Adjustment is 3 mm/ metric. I've never had to Adjust any necks till now I need to adjust the Tele neck. !/4 turn should do it That's it. I'm using the back adj screw. with a straight edge stainless steel flat stock. To bow the neck upward clock wise turn. To curve it counter clockwise. Enjoy.. < concave neck adjustment .

[@markthomas1225]

Great video. The cut-away neck really makes it all clear. I must admit that I previously misunderstood the "double truss rod" concept, thinking that the adjustment could produce either convex or concave fingerboard shapes. Can you confirm that the action is in a single sense (counteracting the effect of the strings) but achieved by the different tension in two rods?

[@warmoth]

+Mark Thomas: You are correct. The Warmoth double-truss rod bends in a single direction, by the use of two different bars anchored to each other. On traditional single truss rods, the bar is anchored to the neck wood itself. There are certain rods that flex in both directions, sometimes called "bi-flex" truss rods, but Warmoth does not use them.

[@KUDGHAT1]

Wonderful explanation !!

[@thedevilinthecircuit1414]

Nostalgia is a powerful drug. Lots of naysayers here, but I can safely guarantee none of them could reliably tell the difference between a standard truss rod and this Gotoh unit in a blind listening test. Many guitar players tend to listen more with their eyes and not their ears.

[@maryannmoran-smyth3453]

One of these came with my warmoth neck which is the best damn neck I Ever owned, this is a great device and I would strongly recommend it the problem is I never have to use it because the neck is so damn good

[@magicdaveable]

I very much prefer the barrel adjuster on my Music Man Silhouette neck. I do like the idea of the side adjust.

[@metalfatigue]

Great video and I learned a lot. I've only been playing since 1966 but I thought the only problem with single truss rods was that some are adjusted at the wrong end. No wonder Leo didn't want to use them. But since I haven't had trouble with old fashioned truss rods, and this double type still only goes one way (good joke, right there) I'm wondering how much weight the double rod and adjustment box add to the neck?

[@glaucocampestre231]

Absolutely enlightening, thank you very much!

[@SvenGoldberg]

Amazing, thank you so much, really helpfull.

[@NiTheGod]

the issue with my neck was that the frets weren't leveled properly, i always thought my schaller floyd rose bridge wasn't leveled, or the truss wasn't properly adjusted. not sure when i bought mine, i think around 2009 surprised that you guys have a youtube channel now lol

[@chipsterb4946]

I mistakenly thought that a double truss rod could make the neck curve either way. IOW force relief (actually counteract excessive backbow) as well as produce backbow. However, this demonstration indicates that the double truss rod is only capable of producing backbow to counteract string tension. If that is the case, the benefits appear to be 1) pressure from adjusting nut is metal on metal (instead of metal on wood), and 2) truss rod channel is a simple, flat bottomed dado of sorts instead of the convex channel require for a single stress rod. Is that correct? Question: are fingerboards thinner, thicker, or the same with a double truss rod? A regular, single-action truss rod applies pressure to the body of the neck. Here it looks like the double action truss rod applies pressure to the underside of the fingerboard, but I may be mistaken.

[@jazzrengue]

Wow!! You guys do great videos!! Awesome.

[@kesamek8537]

Excellent explanation thank you very much.

[@Gin_des]

great video! many thanks

[@guitaristichi]

Thanks for the valueable info!!!!!

[@BlackDotPatrick]

I was hoping to learn how to initially set one up before installing the neck on my guitar.

[@evilcowboy]

The reason people are afraid of their truss rod is they do not know how to set the rest rest of the guitar up after the adjustment and blame the adjustment. All good guitars tailored to a person's needs are done first on feel and comfort if you lack those then any adjustment after that will not be ideal to the player. Personally, I adjust the neck and generally set it as straight as an arrow, the reason I set it to as straight as possible is I believe there is a balance in everything within physics, if the strings are an acting force on the neck then straight should be its balance but all neck are not the same so minor adjustments are made after that to encompass what I feel is comfortable, meaning my comfort zone is a 12 inch radius with jumbo frets with a 25.5 scale length, I know I can set this type of neck straight without an issue and it will be comfortable to me. On my fender strat I need it to be back bowed a bit as those parameters are different I have tried straight and it is not comfortable at all for me. I tend to approach it like "how can I get this neck to feel as comfortable of my other guitars". The comfort of any guitar starts at the neck, and everything that follows reflects that comfort even tone.

[@Easy-Instructables]

Awesome video - Thanks man!!!!

[@BillFranco]

Aaron, I happen to love my necks with the side adjust feature. I've rarely ever needed to adjust any of my Warmoth necks as they are incredibly stable, but when building and setting the intonation, it's just so easy. By the way, on top of being child and pet safe, there're also vegan and gluten free.

[@warmoth]

Oh...good point. We'll get "Vegan and Gluten Free" on the label. I wonder what it would take to have it certified Kosher?

[@BillFranco]

Well, I know I'd feel better about my recent purchase if you guys could make that happen. Could it be retroactive? In all seriousness, I'm getting ready to receive a roasted maple Warhead neck as well as a roasted swamp ash strat body tomorrow. Gonna be a EVH (or Sunset Strip) special - one wood mount humbucker in the bridge and a Floyd. She's going to a tribute guitar for a dear friend that recently passed. Looking very forward to hearing the music from that instrument. Also, I should point out: I have 6 Warmoth builds over the years (I've had students beg me to sell them others I've built) that have gone all over North America & Europe on tour. None have EVER failed me, quitter the contrary - they've been the rock of stability and tone I've been able to stand on in the storm that is touring. You guys kill it!

[@kazkylheku1221]

5:39 Until NECKS time, man. Sorry to say, but this side adjustment mechanism looks like a solution in search of a problem. If you just put the nut on the headstock end, there is no need to take the neck off to access the truss rod. When tweaking the truss rod, you want the strings to be on and in tune, so you can directly monitor the effect on playability and make immediate secondary adjustments like saddle and pickup height, and instantly try everything together.

[@thijs199]

hi I'm replacing a trussrod on a strat with a double action one. I'm pretty sure that smartest way to go about it is to have the trussrod put in a way that when you turn to the right, thus pull on the flatbar of the trussrod it relieves the guitar neck, (in my case, forces the neck to relief) wouldn't you agree? My strat has a pretty stubborn backbow, so much so that the biflex system of fender caused the plug at the headstock to pop out

[@SDA-Sound]

So the Flat Bar of the truss rod, which is closest to the fretboard, actually bends the neck against the string tension? so technically loosening the truss rod would allow the subtle curve of the neck, where as tightening it would straighten the neck? is that opposite of standard truss rods?

[@fredericadda]

Great explanation!

[@heliospuppy257]

Thanks-Great video & very helpful!

[@2121toso]

Great video. Thanks

[@selladore]

That is cool but it's still somewhat limited. It seems to me that the adjustment nut at headstock or musicman type adjustment at heel are better options because you can make even major adjustments without removing the neck

[@bbnatedogg]

I own or have owned over 10 of these necks. I have NEVER had to use the heel major adjust nut.

[@Mosa614]

best explanation

[@FilipeReishandmade]

Great video !

[@jonlennon3348]

I think it is ingenious and the best idea yet. No I seriously doubt it robs tone. All you purists are just resisting change and I cant really tell if it changes the tone much if at all.

[@richardcramp2850]

thanks

[@TheCrowHawk]

So what would constitute a “major” and “minor” adjustment? Does the side nut only tighten a little then?

[@chicagoray1972]

I have one on my guitar neck from warmoth. Just imagine you set the neck prior to installation, then you install and string it up, the strings apply a little bit of tension and bow your neck a bit out of what you had it, this allows you to minor adjust it back, it's an ingenious idea and anybody who doesn't like it is being a curmudgeon. I have been playing since 81 and wish I had this before.

[@gabibonza]

Awesome! 👏👏👏👏👏

[@zvonbackingtracks5264]

I broke side adjusting screw a couple years ago. I dumped the whammy while adjusting but the screw was broken and fell out. Now adjustment is only at heel. The neck is still ok. But this mechanism is not durable... ((

[@michaeldrevyankosr6180]

[@mboyer68]

So..there's a two way truss rod and a double truss rod. The double truss rod is not a two way..correct? It seems that the side adjust would exert more force than the side adjust. Can you please explain why I'm thinking wrong? Thank you! I understand that a screw is a rotary inclined plane, and the side adjust is an inclined plane.

[@normanddeon63]

I'm confused, isn't the double truss rod supposed to have threads on both ends?

[@gloubiboulgazeblob]

So am I : I think Warmoth double-expanding truss-rod IS NOT a two-way truss rod, so if your neck is severly back bowed, the truss rod can't force the neck to go in the other way to fix the problem...

[@Joe-mz6dc]

I think those are called dual-action truss rods. There are a few different designs out there for sure.

[@j_freed]

@@gloubiboulgazeblob - this is technically correct, however in a properly made neck the string tension is all you need opposing the single-action truss rod… I would imagine backbow is likely super rare. Otherwise warranty should cover?

[@user-vl9rz7qr2h]

A bit off the subject on this device, from what l understand or told, PRS even the SE model are equipped with double acting truss rod is this true, and is it better than a single acting truss rod? Thanks again...?

[@nickkellie]

The side adjust Allen is 3mm but what Allen size do I need for the main adjustment at the end of the neck?

[@guitartec]

You should make a video showing how to fix the side adjuster if you unscrew the allen too far

[@1seriousgearheadify]

It stops moving about 8 turns before the screw comes out. Should never happen. You can actually feel the lack of resistance

[@guitartec]

@@1seriousgearheadify If it gets screwed in too far, It can be a real problem.
