Impedance Switch
Utilize the HI/LOW impedance switch to optimize the pedal's performance with different signal chains. Set to HI for high impedance inputs (e.g., direct guitar connection) and LOW for low impedance inputs (e.g., after buffered pedals or line-level signals).
Operating Instructions
Tuner Mode
The Tuner Press features a highly accurate tuner with Strobe and Chromatic modes. The HD LCD screen provides clear visual feedback for precise tuning. When in volume mode, fully elevating the pedal will automatically activate silent tuning.

The Tuner Press offers three distinct tuner display modes for user preference.
Volume and Expression Control
The pedal functions as both a volume and an expression pedal. The footswitch provides tactile feedback, allowing you to seamlessly switch between these two modes. Pressing the toe of the pedal all the way down will toggle between volume and expression functionality. Observe the display changing colors to confirm the active mode.

Maintenance
To ensure the longevity and optimal performance of your Hotone Tuner Press, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners or solvents that could damage the finish or internal components.

Troubleshooting
Display Not Working / Tuner Not Activating
If the LCD display is blank or the tuner is not turning on, consider the following:
- Power Supply: Ensure the pedal is connected to a stable 9V DC power supply. Verify the power adapter is functioning correctly.
- Connections: Check all audio cables (input, output) for secure connections.
- Firmware Update: Some issues, particularly with the display or initial power-up sequence, may be resolved by updating the pedal's firmware. Visit the official Hotone website for the latest firmware and update instructions.
- Mode Toggle: Ensure you are correctly toggling between volume/expression and tuner modes by fully pressing the toe of the pedal. The display should change to indicate the active mode.
No Audio Output
- Cable Check: Inspect all 1/4 inch audio cables for damage or loose connections. Try different cables if necessary.
- Power: Confirm the pedal is receiving power and the indicator lights are on.
- Signal Chain: Test the pedal in a simplified signal chain (e.g., instrument directly into pedal, then pedal directly into amplifier) to isolate the issue.
