I'm playing a G&L ASAT Classic with Rutters compensating saddles. Recently I've been learning some jazz standards and I find it almost impossible to get some chords to sound in tune. A specific for instance would be G7flat9 at the 10th fret. I have tweaked and tweaked at the saddles but things are still a bit off. I'm currently strung with Daddario light gauge 11's. I'm thinking I may need to replace them with 12s with a wound G to get things right.......or is it possible that the intonation of the compensating saddles just isnt exact enough for what I'm working at?
