Location: Maryland, USA | I'm having a problem with the LP guitar I've been rebuilding. Everything is ready, however, when I play on a fretted note, the note is about half a note sharper than it is meant to be on the fretboard. Changing the height of the string on the bridge does nothing, neither does changing the height of the bridge itself.
Any suggestions/ideas? |

Location: Maryland, USA | I've changed the length of the string on the bridge, moved it until I could not shorten or lengthen it any more. The problem is still there.
I'll check on the distance from the nut to the bridge, but I believe it is correct.
I'll get back to you when I measure it. |

Location: NJ | I once played with a guy that decided he needed a new nut on his guitar before we jammed that night. he istalled it 1/4 inch from the beginning of the fingerboard. EVERYTHING we played was out of tune that night and it drove me crazy. We were auditioning a chick singer that night and she never returned. well guess what neither did I, I kept telling him why his guitar was out of tune and he never listened to me.....
many years later.... he is now a lawyer. |

Location: Omaha, NE | Back in seventh grade, when I had dreams of being the next Big Thing in the guitar world, but had no cash to actually buy a guitar, I entertained the fantasy of building my own. I was in shop class at the time, and I figured how hard can this be?
I drew up plans (what I wouldn't give to have those back now!) of a pretty cool looking triangular shaped solid body. I worked out in my mind how to attach the neck to the body (mainly from a careful examination of a friend's Telecaster...God how I envied him!) and even found some cheapo pickups in a pulp-paper music catalog that I figured to be able to afford on a paper-route budget.
But I was stumped by the prospect of cutting the frets into the fingerboard. It seemed to me then (and still does) that that is an operation that requires extreme precision. The slightest variation (either too close or two far from the nut, or worse, off of parallel to the nut) would result in an incurably defective neck.
Eventually, I abandoned my guitar building ideas. Probably a good thing, because a few years later I bought my first Ovation and the rest is history. But this thread got me wondering about the whole subject of fretboard intonation again. Just how critical is fret spacing?
Cheers!

Bridge needs to be moved back,I already found the right spot.
I'll fill up the holes and drill in new ones. |

I had a grill once that, well, never mind... |

Location: Midwest | I used one of these once on a Les Paul many years ago. It worked. http://www.sweetwater.com/store/closeup/PTTP070--Main
It's called a compensating bridge, just in case you don't want to drill new holes. I'm guessing LP meant Les Paul copy.
I should add the model I used had adjustable bridge saddles. |

Location: Maryland, USA | I was able to fix the intonation without adding new holes for a bridge, however the action had to be set extremely high. I'm very unhappy with this setup, so I may try the compensating bridge Dutchman suggested.
Thanks for all the help guys. |
