what tuning are you in and what gauge strings are you using for the rest of the set?
you say "it" is still sharp...are you comparing the note fretted at 12 fret vs the 12th fret harmonic? the harmonic should be the same as the fretted note when the string is tuned to the correct pitch for whatever tuning you are using.
Are you sure the saddle pin is moved to the hole furthest towards the back.
Its b,e,a,d,g,b,e, the string set is 10-56, but I replaced the 56 with I think is a 52. The saddle screw is in the rear spot and its sitting on the incline on the trem. Fretted, the low b is sharp where the open b is in tune.
Oh..let's see the pic from the top...looking down at all the bridge saddles.
What guitar is this?
What is the scale of the neck?
What brand of strings do you have on there?....let's see the packaging.
Dillion 7 string git.
just changed the strings to these; 7-string-regular-slinky-nickel-wound
then popped either a 54 or 52 in place of the 56, but its still would need to go back more.
I had this exact problem with my ibanez, mine is tune to drop A with a 26.5 scale. The intonation struggled with a 60 and with the saddle all back. I had a chat with my guitar tech and now I have a 74 and i took out a little spring so the saddle could move a little further and now it is dead on pitch. A 52 for a B would be quite loose to my understanding and maybe it bends a notch when it is fretted...
I had this problem on my dad's steve stevens hamer for years before i realized it was caused by string-pull from the pickups being too close to the strings. I backed them off and it's fine. Just for ****s'n'giggles, back the pickups off all the way and try it.
