Crazy intonation ?

This just makes no sense to me. It is a Schecter Diamond Series Omen Active guitar in factory setup when I got it to work on. Did the usual clean and lube , string and intonate. This is where the saddles ended up and some of them are still flat Just plain crazy and against the laws of physics.
 
Re: Crazy intonation ?

Measure the nominal scale length. Perhaps it is a positioning error. A poorly cut nut can cause all kinds of intonation problems as well. What is the relief and the action?
 
Re: Crazy intonation ?

what string gauge? what tuning?

and +1 to everything LakePlacidBlues said.
 
Re: Crazy intonation ?

10s , 440 I just eyeball relief and it looks pretty straight and true , as in it matches on all the strings too. Nut is factory GraphTech Tusq XL , looks if anything was wrong with it , the strings sit pretty close to the first fret. That would make it sharper not flatter

You may need one of these...

Re: Crazy intonation ?

hmmm.

what`s your method for checking/setting intonation?
 
Re: Crazy intonation ?

Tune the guitar check the harmonic at the 12th, fret at 12th intonate , sometimes I use 2 tuners one on stream one on cent Boss TU 2 & 3 nothing fancy but they work just fine. I turned the saddle around because that one was close enough , it isn't alot but the guy that owns it really just wants it close enough not to sound bad. He doesn't have very high expectations for the cheap guitar , he bought it mostly to help out the local music store guy (he is really nice like that).
 
Re: Crazy intonation ?

that's weird man, i use the same method, but i've never had any saddle arrangement end up as drastically different as what you posted.
 
Re: Crazy intonation ?

Why dont you turn the rest of the saddles around?

How flat is flat? If its close then turning the problems around will get you there? Or am i missing something obvious?

I'd also go to the length of playing the fretted notes for 12 back to 1 to see how that goes too. I find just using the 12th fretted vs harmonic practically useless as a method to get fretted notes in tune.
 
Re: Crazy intonation ?

Ahh i can see what went wrong now. I think you put the bridge on around the opposite way.

Turn it back around so that the slopping side of the saddles faces the tailpiece. This should give you that added room needed for intonation.
 
Re: Crazy intonation ?

Bridge is on backwards, the heads of the adjustment screws are supposed to be facing the bridge pickup.

Re: Crazy intonation ?

Turned around bridge and it is fixed yeesh. If I only had a brain. Thanks guys. AlexR hitting the harmonic on the 12th fret is a control to test that the guitar will intonate properly , if the harmonic is out of tune when the guitar is in tune you have scale and or misplaced fret issues.
 
Re: Crazy intonation ?

True

Yes, it is commonly what I use to start the intonation process too. Depending on how the guitar is set up, fret heights, string gauge etc I find that you have to tweak this control position quite a bit to then get the intonation sounding as good as it can for that guitar.
