Troubleshooting tuning issues for Kahler CAM systems only.
Symptom:
All strings return flat after pull up and/or sharp after dive.
Reason:
This is a global issue caused by dragging preventing the CAM from coming back to zero or you are using Ernie Ball strings. Click here to learn more.
Where:
Cavity not deep enough. CAM rubbing on cavity sidewalls. CAM interferes with ground wire. String lock or Locknut is not gripping strings tight enough. Rollers too high? Rollers are dirty and wont spin. Springs are over 3 years old?
How:
Route the cavity 1 inch deep. Re-align tremolo on guitar so CAM does not rub sides. Re-adjust the ground wire and fasten it if necessary. Check for locking device on neck for wear, replace if necessary. Lower string rollers to help stability. Disassemble, clean thoroughly and reassemble the string rollers if dirty. Change the springs if over 3 years old. Change your strings to a set recommended for Kahlers. Do not use Ernie Balls.
 
Symptom:
G String goes flat after string bend.
Reason:
This is a singular string path issue. This has to do with the type strings you use and/or the locking mechanism on the neck.
Where:
The "2 string per clamp plate" string locks and locknuts and/or the knots that tie the G string around the ball end can both be the culprit. Click here to learn more.
How:
Turn the clamping screw on the necks locking device, tighter. Use Reinforced or Tremolo strings only.
 
Symptom:
Strings will not stay in tune anymore. Always retuning.
Reason:
This is a global issue.
Where:
Strings are old. Springs are fatigued. Tremolo/bridge string rollers are dirty.
How:
Get new springs today. PN#8412 or PN#8413 for Bass. Change your strings, Get tremolo strings. A Kahler is like a gun, keep it clean and it will never fail you.
 
Symptom:
There is a clicking or clinking sound when I do a string bend and the string comes back flat or sharp.
Reason:
This is a singular string path issue.
Where:
It can be a string making a noise as it scrapes across a nut or thru a locking device that is not tight enough.
How:
Flute the in and out of each string slot and lubricate the nut slots. You can also get a Graph-Tech Black Tusq XL, Teflon nut.
