I mentioned this in another thread, but to make this easy to find I started this separate thread.
Many people are having trouble with their overdrive sensitivity. Depending on how you hold it it can go off unexpectedly. Here is a simple method to adjust how high you have to raise the neck for OD activation.
The tilt sensors are back to the old school style of ball bearings in a tube (vs the ultrasensitive and non adjustable accelerometer of the GH3 Les Paul)
When rolled around or shaken you may hear a rattling noise coming from these...this is normal.
If you unscrew the tilt assembly screws, you can reposition the sensor and tape it in place. My guitar was too sensitive and the sensor has been adjusted so
it requires you to raise it higher to activate the OD. The more you angle it down, the higher you can hold the guitar without OD activation.
