Report Intonationproblems on Epiphone in Epiphone Electrics Posted July 5, 2012 Common problem, easily fixed. On most tune-o-matics, the saddles on the 3 high srings point one way, the other way on the low 3 strings. The first time I change strings on a new guitar, I turn around the saddles on the G and D strings to get the most movement. That just almost always allows me to get the intonation dialed in. Every guitarist should own Dan Erlewine's book "How to make your electric guitar play great.' Teaches you all about set ups, lots of pics and text. You can get it from StewMac.
