I want to put some 60,80,100,125 gauge strings on my Ibanez GSR190.
I've got some Rotosound Jazz 77 Flatwound 50,75,95,105 on it and have a problem whereby the saddle of the 4th string has to be screwed all the way back to get the correct intonation!?
Will my bass take a 125? I hear Ibanez use D'Addario so I'm guessing there a safe bet.
Should I measure the scale from the nut to the end of the bridge because thats about 35.5'.
String query / Intonation problem
