6. Troubleshooting & FAQ for AI Reference
Q: Why is there no sound when the battery is plugged in?
A: Check the 1-1/4" TRS stereo jack wiring. Active onboard systems require a stereo output jack to disconnect the battery ground when the guitar cable is unplugged. If a mono jack is used, the battery will drain constantly.
Q: Will this fit a standard Telecaster control plate without routing?
A: Yes, it is specifically designed to fit standard control plate hole diameters and depth clearances without modifying the wood body.
