Aster1 Posted October 28, 2012 Share Posted October 28, 2012 Hi Ya'll. I'm a little stumped as this new Casino intonation will setup just great on E & D but the A string is "flat" on the fretted 12th vs the intonated 12th fret. I have run the tune-o-matic all the way up towards the Bridge Pup and still flat. Also reversed the direction of the saddle metal adjuster to gain just a bit more on that. Still flat. Rest of the guitar's intonation just fine, ONLY THAT DANG "A" string. Any suggestions? Thanks Aster Link to comment Share on other sites More sharing options...
L5Larry Posted October 28, 2012 Share Posted October 28, 2012 Before you get too upset and think you have a major problem, try a different set of new fresh strings. Even if you are working with new strings, try another set. As the typical "A" string saddle position will be between the E & D (and they both intonate), I suspect a bad string.

Aster1 Posted October 28, 2012 Author Share Posted October 28, 2012 Thanks for the tip. I was going to re-string but was wondering what I'd be doing if that didn't cure. Just a dumb question and not doubting things, but what exactly can a string do to cause that situation? Thanks again, Aster Link to comment Share on other sites More sharing options...
stein Posted October 28, 2012 Share Posted October 28, 2012 If the string does not vibrate consistantly the whole length, it will be different where you play it. That can be from windings being tighter, or inconsistant thickness, ANY physical property, really. It is actually common for a string to get a little damage on a winding, or get a kink. But regardless, it can be a string. It IS odd that the E and D intonate, and the A doesn't. Obviously, because usually, the A saddle will be between the 2. Another thing that can cause the intonation to be different, is the hieght. It might be a case where the slot in the saddle is cut different. Remember also, when doing intonation, don't just do it according to the twelth fret- check ALL the fret positions. Link to comment Share on other sites More sharing options...
Aster1 Posted October 28, 2012 Author Share Posted October 28, 2012 Thanks for the detail on the "string thing" Stein!! You know when Enquiring (sp) minds just have to know things!! I will check into this some more right now as I've had all the Online pre-training training I can handle for my training trip tomorrow. Sheeesh, I hope I won't need a pre-pre-training session prior to my pre-training course before my training course next time!!! Have a great week everyone!! I don't know if I'll stop in to play some Hummingbirds in KC or not. Hope I have time. Aster Link to comment Share on other sites More sharing options...
jeff737jeff727 Posted October 31, 2012 Share Posted October 31, 2012 What gauge/brand strings are you using? You may have difficulty with .009 gauge. Link to comment Share on other sites More sharing options...
Aster1 Posted November 1, 2012 Author Share Posted November 1, 2012 I have factory .11's on it, but will change to .10's this weekend I think. Aster Link to comment Share on other sites More sharing options...
Greybeard Posted November 1, 2012 Share Posted November 1, 2012 I've had some luck with a string that was running out of adjustment on intonation by detuning the string down a few steps, running the adjustment screw on the bridge in the opposite direction almost to the opposite stop, then retune the string open and try the intonation adjustment again. I can't explain why it works but it did seem to solve the problem. It appeared to me that the bridge saddle was too close to the stop when I started the intonation setup and by backing it off from where I started and doing it over it cured the problem. If I'm not explaing it clearly just ask and I'll try again. Link to comment Share on other sites More sharing options...

disaster Posted November 3, 2012 Share Posted November 3, 2012 If you can't move the saddle any further towards the tail of the guitar you can try raising the bridge. This will give the same effect as lengthening the distance between the nut & bridge. Unfortunately it will raise the action. You can just raise one side of the bridge to minimize the impact on the action of all the strings. Unless thicker strings help the only other choice is an increased bridge height. You can also shop for taller saddles and replace them instead of raising the bridge height screws, but the effect will be the same & it's more work. Good Luck Link to comment Share on other sites More sharing options...
Pete B Posted November 4, 2012 Share Posted November 4, 2012 A higher than the other strings slot on the nut could cause it Link to comment Share on other sites More sharing options...
RIX Posted November 4, 2012 Share Posted November 4, 2012 Aster1, I notice in reading your post you didn't mention that you completed a setup before trying the intonation. It case you find it is not the string or nut slot; it is very important that you go through the correct sequence for intonation to work properly. After you have installed new strings and stretched them. 1. Check relief and adjust if necessary to at least the manufacture's spec. 2. Check the radius of the fretboard and compare it to the string at the saddles. 3. Check string height and adjust to at least the manufacture's spec. 4. Check the nut action and adjust accordingly. 5. Check and adjust intonation. If you skip any of the preceding checks/adjustments or do them out of order you'll have problems. The manufactures spec is a starting point, most people will set it lower if they have no string buzzing. And it depends on your style of playing. Also you might try using a clip on tuner rather than one you plug the guitar into. This way you eliminate the electronics and you know that for sure that the intonation is spot on. You'll that when you plug your guitar into your tuner it is spot on. Hope that helps. Link to comment Share on other sites More sharing options...
Whitmore Willy Posted November 4, 2012 Share Posted November 4, 2012 All above are providing good info and suggestions. If all above is followed and there is still a problem consider.... Sometimes a certain brand of strings can react slightly different on different guitars. Also, some strings just act strange on some guitars...I have a similar intonation problem with the way my low E string acts on one of my guitars. It just vibrates funky. Maybe it's the wood, maybe voodoo spirits??? One of the things I have noticed with that particular string is that the 12th fret harmonic it settles into is different then the one I get upon immediately striking the string. Guess what? How often do you play a note for a few seconds? Even when strumming a chord, most actual notes only play for a fraction of a second. 99.9% of the time. Once I started to intonate (and tune) with that in mind the string was no longer a problem. Whatever it turns out to be,,, Good Luck, Willy Link to comment Share on other sites More sharing options...
