TC Electronic Infinite Sample Sustainer Guitar Effect

Capture and Sustain a Moment — TC Electronic Infinite Sample Sustainer

The TC Electronic Infinite Sample Sustainer is a guitar effects pedal that samples a snapshot of your playing and freezes it as an endlessly held ambient pad. Strike a chord, tap the footswitch, and the pedal sustains your tone indefinitely so you can play lead lines over the top. The Infinite Sample Sustainer is the right choice for ambient, shoegaze, and experimental guitarists who want to turn a single note into a full evolving soundscape.

Layered Sampling, TonePrint Customization, and an FX Loop

Four sampling modes — L1, L2, L3, and Infinite — stack single notes into chords or layer chords into morphing textures. Three TonePrint slots accept custom or artist presets beamed from the free TonePrint app, with full access to sample rate, EQ, reverb, and modulation. A send/return FX loop applies external effects to the sustained signal only, so distortion, flanger, or octave pedals can color the pad while your dry guitar tone stays untouched.

Front-Panel Controls — Real-Time Sound Shaping

The four-knob layout gives direct access to the most important sustain parameters without diving into the app, with the FX Type knob selecting between L1, L2, L3, Infinite, and three TonePrint slots from the top of the pedal.

• Level: Sets the output volume of the sustained signal — match the pad to your dry guitar or push it forward in the mix
• Decay: Controls the release time of each held sample — short for tight swells, long for slowly fading drones
• Fade In: Adjusts how quickly new layers enter — instant capture or gradual blend

I/O and Signal Path — True Bypass and Analog Dry-Thru

Standard instrument cables connect the pedal into any guitar rig, and the Analog-Dry-Thru design keeps your original guitar tone completely uncolored even while sustain is active.

• Inputs: 6.3 mm TS jack — standard mono instrument input compatible with any electric guitar or bass
• Outputs: 6.3 mm TS jack
• True Bypass: Yes — mechanical relay bypass preserves your tone exactly when the pedal is off

Power, Footswitch Modes, and Footprint

The compact 122 × 74 × 50 mm, 340 g chassis runs on a standard 9 V DC supply and offers two footswitch behaviors to match different playing styles.

• Power: 9 V DC — runs on any standard isolated pedalboard power supply
• Battery Powered: No — designed for permanent pedalboard installation with mains power
• Footswitch Modes: Latching or Momentary — latching for hands-free drones, momentary for piano-style sustain control
