Gamechanger Audio Plus Pedal II Sustainer

The original Plus Pedal brought real-time audio sampling to musicians everywhere, letting virtually any instrument sustain like a piano. The Gamechanger Audio Plus Pedal II takes that groundbreaking concept and rebuilds it from the ground up, combining the original tech with an all-new Spectral Sampling engine.

Rather than simply freezing notes, it captures and preserves the harmonic detail, dynamics and character of every sound. That means it delivers an incredibly natural and responsive sustain experience for guitars, vocals, strings, brass, keys, anything!

Smarter layers, greater expression

With Auto Layer Catch, the Gamechanger Audio Plus Pedal II intelligently detects and captures new notes while filtering unwanted noise and managing transitions seamlessly. Hold the pedal down and play as rich layers build beneath your performance. A dedicated Layers control lets you choose anything from a single crystal-clear sustain to complex multi-layered textures, or even Infinite mode for endlessly evolving soundscapes. An LED halo display provides instant visual feedback, while the new optical pedal control lets you shape volume and release characteristics.

Dynamic sound design at your feet

The Plus Pedal II goes far beyond traditional sustain with dual resonator engines that continuously react to your playing, generating evolving upper and lower harmonics that bring motion and depth to every layer. The Tone control applies a dynamic filter envelope to each one individually, helping sustained sounds breathe and develop organically. Advanced Catch, Hold, Rise and Decay controls give you complete command over how layers are introduced, evolve and fade away, making it easy to create everything from simple chord accompaniment to cinematic ambient textures.

Flexible routing & expanded control

The smart FX loop now includes three routing options that let you place external effects before the pedal, on the sustained layers only or across the entire output mix — all at the flick of a switch. This opens up huge creative possibilities with delays, reverbs, modulation, pitch-shifting and more. An optional external footswitch further expands the pedal’s capabilities with Wet, Latch and Hide modes, giving you even greater flexibility for both live performance and studio work.

Here’s a roundup of the Plus Pedal II’s key upgrades:

• Smart stereo FX loop: Use a three-position switch to route your effects before the sustain engine, on the sustained layers only, or after the Plus Pedal II for completely different sonic results.
• Spectral Sampling engine: Captures the true harmonic and dynamic character of any input, delivering a more natural and responsive sustain experience.
• Layer control: Choose between 1 and 10 active layers, or engage Infinite Mode for stacked ambient textures and soundscapes.
• Auto Layer Catch: Hold the pedal down and play as normal while the Plus Pedal II intelligently captures and layers every new note!
• Dual resonator + dynamic tone: Create rich, evolving harmonic movement with responsive upper and lower resonances that react to every active layer.
• Combo XLR/TS input & built-in mic preamp: Capture guitars, vocals or acoustic instruments directly with the studio-grade mic preamp and adjustable gain trim pot.
• Optical pedal control: Enjoy smooth, expression-style control over sustain volume and release characteristics across the pedal's full range of movement.
• Circular LED halo display: Monitor active layers and pedal status at a glance with clear, real-time visual feedback.
• Advanced hold & decay controls: Fine-tune how layers are captured, sustained and fade away for everything from subtle accompaniment to immersive ambient washes.
• Optional external footswitch: Expand your workflow with dedicated Wet, Latch and Hide modes for enhanced live and studio performance flexibility.
