[rurounisld]

Anyone can help me here ?

what can i do if my t rod is not moving at all? i ve loosened the string and let the neck for 8 hours but it won't move at all

[cod4boys]

its impossible to look at your neck

xxxxx.203

.008 .254

.010 mm

I put x's to move over the .203 so it was post right.

[Nagromman]

@SuperGuitarpractice .008" is inches and .203 is mm. .008" * 25.4 = .203mm

[SuperGuitarpractice]

I bought the gauges from auto zone and they are stamped like this .203

.008 .254

.010 mm

I'm not sure if they are saying .010 mm or .254 mm

Thanks for your help

[Nagromman]

@icansmellcyanide Yes definately stop when you lots of resistance. You don't want brake your neck or lift the fretboard from the neck.  You shouldn't have to turn truss very much.

[SuperGuitarpractice]

metric?

[Nagromman]

@SuperGuitarpractice multiply by 25.4 thats the conversion to mm. Eg .008" x 25.4 = .02mm

Great instructional vid!

Just two questions:

1. Where can one buy feeler gauges--Lowes or Home Depot?

2. For trus rods in the sound hole, is it necessary to loosen strings before adjusting? In my case I need to loosen the rod to raise action because of fret buzz, but I'm not sure if I should loosen or remove strings first. thanks!

[Nagromman]

@jjjjbarton you can buy feeler gauges at a machine tool supply store.

e.g. Production Tool Supply.

Yes its necessary to loosen the strings before adjusting the truss rod for guitars that have the adjustment inside the sound hole. Not nessary for truss rod adjustment located at the headstock.

Hi, do you need to adjust the saddle at the same time you're doing this or it can be done on its own? Thank you for a great video & clear explanations.

[Nagromman]

@bottaleau No you should not remove material from the saddle at all. Thats entirely different adjustment.

on another site, it says to measure the gap at the 7th fret. is there a difference?

[Nagromman]

@psjeong The differance is very small, on acoustic guitar I would always measure at the 6th fret but for an electric guitar I would measure at the 7th fret. Another way of looking at this measurement is to measure LENGTH from the NUT to were the neck and the body meet. On most acoustic guitars the body meets the neck at the 14th fret. Anyways use that length to calculate the centre distance of the neck by dividing by two. That length will probably be slightly under the 6th fret.

I went to a technician and asked him to adjust it for me. He told me that it's best for him to adjust it and then let the guitar rest for a day or two and then repeat the process again until it's perfect. The fastest he can make it is 2 to 3 days. Is it necessary??

[Nagromman]

@TanYangPengMusic If its a brand new guitar thats never been stringing or if its an older guitar that hasn't been stringing in along time, then yes that would be necessary.

If you went from say a light to medium string thickness you would have to allow for break in time as well.

If you don't have any of those issues then it wouldn't be necessary to wait.

[jonnyXrice]

On your acoustic it's the 14th fret that marks the end. But what about a cut-away body OR guitars with jumbo frets?

[Nagromman]

@jonnyXrice the reason why you press down the 14th fret is because thats roughly the length of your truss rod as I show at the begining. The truss rod will curve the most around the 6th or 7th fret. You want always take your measurement from the widest gap between the top of the fret and the bottom of the string.

you didn't mention which way to turn the key to bend the neck back ,ie clockwise or anticlockwise?but the rest is good,thanks,i have a truss rod for a mandolin i'm attempting to make,it has a flat bar with a round bar with thread ,i don,t know wether to put the flat bar to the fret board or the neck or does it not matter?what do you reckon?cheers Jake.

[pumpwithchuck]

it was a good video i helped to adjust neck relief

[merahim]

plz tell me my guitar strings is to high to the neck in wich way i have to turne the truss rod well thanks and sorry for my inglish

[rogerwilco59]

Nice video, I have a question do you use the feeler gauge for all the strings or just the Big E?

[Nagromman]

Use the feeler gauge on the big E only.

the reason is the big string will most likely buzz first if action is to low.

[rogerwilco59]

Thanks for the fast response.

[MrILikeMike]

@Nagromman, Hi I have an epiphone ej200, it is in tune but it doesn't sound right will I need to adjust the neck or can it be something else, thanks mike.
