The Warmoth Double Truss Rod & Side Adjustment Mechanism Explained 

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.

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

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

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.)

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.

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

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.

Realy?

@Billie Goes get a life loser

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

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

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

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!

+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.

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

The main advantage of a double truss rod system is that all the inward tension being generated by the rod is absorbed by the rod itself, and not by the neck wood. Over time this constant inward pressure can cause some necks to develop a hump or an S-curve. That doesn't happen on double truss rod necks, because that inward pressure is not being born by the wood. It also makes them far more stable, as opposed to traditional single truss rod designs, which often need seasonal adjustment.

Also, if you're wondering why we can't just orient our double truss rod so that it adjusts at the headstock and get rid of the side adjust mechanism, the answer is: we can and do....but only on our tiltback headstocks like the Nomad and Hombre. On straight headstocks like the Strat or Tele replacement necks we can't. The geometry doesn't work, due to the fact that double truss rods sit in a perfectly flat trench while at rest, as opposed to curving up at the ends like single truss rods do. IOW, you can't get to the adjustment nut at the headstock because it's sitting too deep in the neck. Hope that makes sense.

I guess I should have watched every video, read every single comment befor ordering my neck. There was no indication that modern construction meant a truss rod or another part. I've got 12 guitars that don't have a double truss rod and all are more stable than the one one double truss rod.

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...

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

@@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?

Double truss rod and double action are two different things, Warmoth is a double truss rod/single action, Fender Biflex is single truss rod/double action, some others are double truss rod/double action, and the vast majority is single truss rod/single action.

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.

yes, I hope that gives you some relief

@@robertjohnson1681 if it didn't gave you enough relief you can do major adjustments at heel...

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

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

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.

Thanks so much for the response! Can you comment further on why you don't use bi-flex truss rods?

@@5urg3x because the string tension provides the pull in the other direction. The whole point of the truss is to counter that

@@prd004.2 Of course, but wood is a strange animal. It reacts to climate and humidity in ways that can cause it to twist and warp in any direction really. The tension capable of being applied from a truss rod is orders of magnitude greater than the tension coming from the strings, even if heavy gauge strings are used. And if the player is using 9s or lighter, on a 25.5" scale guitar, with no wound third, that's barely any tension at all.

@@5urg3x Nick, great response. Love my Warmoth neck, but could REALLY use some neck relief. With 9s or 10s, there is really not enough tension to provide relief. Otherwise, the neck just lays flat, requiring sting action to be a bit higher than preferred. And, I have a wenge next that appears to have less "give" than typical neck woods.
