hi everyone, I have build some more CBG guitar, and used both scalelenght and fretboard calculator to get it right. Tune to GDG, I using youtube to learn the how to play, but my CGB sounds like S...! it sounds oki with a slide but when i´m trying to learn Amazing Grace og Cottonfields as showed by Glenn Watt it does not sound anything like that. Have I build them wrong or what? Maybe picture from me would help. If there is any who have some sparetime to help, it would be great.
Maybe contact on Email firstname.lastname@example.org
Kind regards Thomas, Denmark
hummm. My first suspicions would be :
1- Placement of the bridge is off a bit ? (measure from the middle of the nut to the 12th fret , that should be exactly half the scale . or the same measurement from the 12th fret to the middle of the bridge.)
2- Your action is too high (strings are too high off the fretboard and become sharp when pressed down on .
3- your nut may be off , or where the strings ride are not in scale ,
First 2 are easy fixes,
a picture from the side to see how high the strings are may help .
thanks for answer I´´m sending som picture of the guitars
As I have written I have done a scale length so from nut to 12tf should be the same as from 12th til bridge
I have thought about the string action have can I prevent that, put in some smaller bridge ?
what does it mean nut is off? strings are not in scale?
Yes , your string action is a bit high on all of them . a smaller bridge and nut should help on nr 2 and 3 . But your First picture , the neck is lower than the body , so a smaller bridge may not work without the strings bottoming out on the body while strumming .
(nut is off? strings are not in scale?) Means the measurement should be from where the strings contact point is on the nut . (usually around the middle of the nut ) if you are measuring from the side of the nut , the measurment will not be correct.
Hi, for me it's hard to diagnose a problem like this without having the guitars on the bench.
In my experience your action, string height, looks ok, not too high to make the guitar play " nothing like" the piece you are learning anyway. I use very high slide action but compensate my bridge accordingly. It still notes in the "ball park" when fingered.
High action at the 12 fret will effect correct noting in that area and above, it should still play in tune- ish at the first 5 frets. If it is out of tune at the nut end then the strings are too high at the nut.
However, I would check every thing you have done.
Scale length... from where the string leaves the saddle to where the string leaves the nut
Intonation.....pick open string and then pick fretted at 12 fret should sound the same only an octave higher
Move the bridge back or forewads, normally back, until the two notes sound the same, only an octave apart.
I would also look at your fret spacing....You say it plays/sounds good with the slide, BUT..are you holding the slide over the top of the fret or unknowingly compensating for incorrect fret positioning?
When fretting a note finger goes behind fret string hits centre of fret (unless fret has a flat top, but that's another issue) the slide should sit over the same area to get the same note.
Check fret spacing.
That's going to pull notes sharp if fretting and sound off for sure. Maybe a hole step.
Strings need to be high for slide - low for fretting. Setting up a git for both is difficult and takes a good bit of practice to play both well. I usually set the string height at 3/16" off the fretboard to play both and about half that for fretted. String height over the top of the body is usually higher than the fretboard height and that is fine.
Distance from backside of nut to 12 fret is half the distance of the scale length, but 12 fret to bridge/saddles will be a bit longer to to intonation/compensation.
Measuring frets before cutting slots should be done from the nut to each fret, not fret to fret. Because if you get a fret off the mark, all the rest will be off the mark.
Thanks Pick, I never thought of blowing it up. Yep that should play ok at the nut [ at least it should sound like Amazing Grace] if the Bridge is moved to allow for the higher action.
On the guitar I just played/posted in the video section, the 12th fret action is 4mm and 1st fret 1.5mm and with the bridge compensated for that, it intonates perfect, just a bit sharp at the nut as the strings are tighter there.
That's what makes me think the problem is other than string Hight. But I could be wrong, we can only surmise what the problem is without having the actual guitar I suppose.
