Tuning problems

[Rick Hopkins]

I have tried all i know to do but i cant get my cbg to play and not be sharp up and down the neck its constant i tune to open g chord gdg for the 3 strings but any note i try to frett shows sharp on my tuner the strings are .025,.020,.015 there is a .050 gap between the first frett and a .130 gap between the 12th frett and the string if i use a slide all is good thanks for any help

Try moving your bridge back toward the tail to increase the scale length. Move it about 1/2" ,  retune and check it. That should show better results, at least it's a starting point.

What Jim said. awhile back I made a cbg that was fretted 628mm but bridged at 648.....took some head scratching until I worked it out.

rick, .20 between 1st fret and strings, the higher the strings makes them act like bending ,your making them longer when you fret them.
