Introduction
The TC Electronic Infinite Sample Sustainer is a versatile guitar effects pedal designed to sample and sustain your guitar signal, creating rich, ambient pads for you to play over. It features optional layering, an infinite mode for continuous morphing layers, and integrated reverb and modulation effects. The footswitch can be configured for either latching or momentary operation, providing flexible control over your sound.

Setup
Power Connection
The Infinite Sample Sustainer pedal requires a 9V DC power supply with a center-negative polarity. Ensure the power supply provides at least 100mA. Connect the power supply to the DC input jack located on the rear of the pedal.
Audio Connections
- Connect your guitar or other instrument to the IN jack on the right side of the pedal using a standard 1/4" instrument cable.
- Connect the OUT jack on the left side of the pedal to your amplifier or the next pedal in your signal chain using another 1/4" instrument cable.
- For advanced routing, utilize the SEND and RETURN jacks to integrate external effects into the pedal's internal FX loop. This allows you to apply other effects specifically to the sustained signal.
USB Connection
The USB port on the rear of the pedal is used for connecting to a computer for firmware updates and TonePrint editing. Use a standard USB cable to connect the pedal to your computer.
Operating the Pedal
Controls Overview
- DECAY Knob: Controls how quickly the sustained sound fades out. Turn clockwise for longer sustain.
- LEVEL Knob: Adjusts the overall output volume of the sustained signal.
- FADE IN Knob: Determines the speed at which the sustained sound fades in after the footswitch is engaged.
- FX TYPE Knob: Selects between different effect types (L1, L2, L3, Infinite, TP1, TP2, TP3).
- L1, L2, L3: Layering modes, allowing you to stack multiple sustained notes or chords.
- Infinite: Creates an indefinite number of layers that gradually morph together, ideal for ambient textures.
- DRY/VERB Switch: Toggles between a dry sustained signal and a sustained signal with integrated reverb.
- LATCH/MOMEN Switch: Configures the footswitch behavior.
- LATCH: Press once to engage sustain, press again to disengage.
- MOMEN (Momentary): Sustain is active only while the footswitch is held down.
- Footswitch: Engages and disengages the sustain effect based on the LATCH/MOMEN switch setting.
Basic Operation
To activate the sustain effect, play a note or chord and then press the footswitch. The pedal will capture and sustain the sound according to your settings. Experiment with the Decay, Level, and Fade In knobs to shape the sustained sound. Utilize the FX Type knob to explore different layering and infinite sustain possibilities, or load custom TonePrints for unique effects.
Maintenance
The TC Electronic Infinite Sample Sustainer pedal is built for durability. To ensure its longevity and optimal performance:
- Keep the pedal clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Protect the pedal from extreme temperatures, humidity, and direct sunlight.
- Disconnect power when not in use for extended periods.
- Regularly check all cable connections for secure fit.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound when pedal is engaged. | Incorrect power supply, faulty cables, incorrect connections, Level knob set too low. | Verify power supply (9V DC, center-negative, 100mA minimum). Check all instrument cables. Ensure IN and OUT jacks are correctly connected. Increase LEVEL knob. |
| Sustain cuts out too quickly. | DECAY knob set too low, LATCH/MOMEN switch set to MOMEN. | Increase DECAY knob setting. If continuous sustain is desired, ensure LATCH/MOMEN switch is set to LATCH. |
| Sustained sound is distorted or noisy. | Input signal too hot, faulty power supply, ground loop. | Reduce input signal level from your instrument or preceding pedal. Try a different power outlet or isolated power supply. Check for ground loop issues in your setup. |
| Cannot load TonePrints. | USB connection issue, outdated TonePrint app, incorrect pedal mode. | Ensure USB cable is securely connected. Update the TC Electronic TonePrint app to the latest version. Follow app instructions for loading TonePrints. |
