Introduction
This manual provides comprehensive instructions for the Fender Tone Master Princeton Reverb Guitar Amplifier. This 12-watt solid-state combo amplifier utilizes advanced Tone Master technology to accurately replicate the sound and response of the classic Princeton Reverb tube amplifier. It features a 10-inch Jensen C10R ceramic speaker, authentic reverb and tremolo effects, selectable output power, balanced line output, onboard speaker emulation, and a mute switch for silent practice or recording. Please read this manual thoroughly to ensure proper operation and to maximize your amplifier's potential.
Setup
Follow these steps to set up your Fender Tone Master Princeton Reverb amplifier:
- Unpacking: Carefully remove the amplifier from its packaging. Retain all packing materials for future transport or storage.
- Placement: Position the amplifier on a stable, level surface. Ensure adequate ventilation around the unit.
- Power Connection: Connect the supplied power cable to the amplifier's AC inlet and then to a grounded electrical outlet. Ensure the amplifier's power switch is in the 'OFF' position before connecting.
- Instrument Connection: Connect your guitar to one of the 'INSTRUMENTS' input jacks (Input 1 for normal sensitivity, Input 2 for reduced sensitivity) on the front panel using a standard 1/4-inch instrument cable.
- Initial Power-On: Turn the 'VOLUME' knob to its lowest setting. Flip the power switch to the 'ON' position. The power indicator light will illuminate.

Operating Instructions
Familiarize yourself with the amplifier's controls for optimal performance:
- Instruments Inputs (1 & 2): Input 1 provides full sensitivity, while Input 2 offers -6dB attenuation, suitable for higher output pickups or to achieve cleaner tones.
- Volume: Controls the overall output level of the amplifier.
- Treble: Adjusts the high-frequency response.
- Bass: Adjusts the low-frequency response.
- Reverb: Controls the intensity of the built-in spring reverb emulation.
- Speed: Adjusts the rate of the tremolo effect.
- Intensity: Adjusts the depth of the tremolo effect.
- Output Power Selector: Located on the rear panel, this switch allows you to select various attenuated output levels (e.g., 12W, 6W, 3W, 1.5W, 0.75W, 0.3W) to achieve desired tone at different volumes.
- Line Output: A balanced XLR output on the rear panel provides a direct signal for recording or connecting to a PA system. It includes switchable speaker emulation.
- Mute Switch: Engages a mute function for silent practice with headphones or for recording without speaker output.

Maintenance
Proper care will ensure the longevity and performance of your amplifier:
- Cleaning: Use a soft, dry cloth to clean the exterior of the amplifier. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the amplifier in a dry environment, away from extreme temperatures and humidity. If storing for extended periods, cover the amplifier to protect it from dust.
- Ventilation: Ensure that the amplifier's ventilation openings are not obstructed during operation or storage.
- Transportation: When transporting the amplifier, ensure it is securely packed to prevent damage from impacts.
Troubleshooting
If you encounter issues with your amplifier, refer to the following common problems and solutions:
- No Sound:
- Check if the amplifier is powered on and the power indicator light is illuminated.
- Ensure all cables (power, instrument) are securely connected.
- Verify that the 'VOLUME' knob is not set to zero.
- If using the mute switch, ensure it is disengaged.
- Test with a different instrument cable or guitar to rule out external equipment issues.
- Distorted or Unclear Sound:
- Adjust the 'VOLUME' and tone controls (Treble, Bass) to find a balanced sound.
- If using Input 1 with high-output pickups, try Input 2 for reduced sensitivity.
- Ensure the guitar's volume and tone controls are set appropriately.
- Effects Not Working:
- Check the 'REVERB', 'SPEED', and 'INTENSITY' knobs to ensure they are not set to zero.
If problems persist after attempting these solutions, please contact Fender customer support or an authorized service center.
