6. Troubleshooting
| Problem | Possible Solution |
|---|---|
| No power | Ensure the power adapter is correctly connected and the power switch is ON. Verify the power adapter specifications (9V DC, center negative, 300mA minimum). |
| No sound output | Check all audio cable connections. Verify the MASTER volume knob is turned up. Ensure the selected preset has active effects and appropriate volume levels. Check your amplifier/monitor volume. |
| Distorted or unwanted sound | Check input gain levels on the FX150 and your amplifier. Adjust individual effect parameters (e.g., gain on overdrive/distortion). Ensure correct connection method for your setup (e.g., amp modeling should be off when connecting to an amp's input). |
| Footswitches not responding | Check footswitch assignments in the settings menu. Ensure the unit is not in a mode that overrides footswitch functions (e.g., tuner mode). |
| Cannot connect to computer | Ensure the USB-C cable is securely connected. Install the necessary drivers for the FX150 on your computer. Try a different USB port or cable. |
