Gamechanger Audio PLUS Pedal II

Gamechanger Audio PLUS Pedal II – Piano Sustain for Guitar, Vocals and More

The Gamechanger Audio PLUS Pedal II brings the feel of a piano sustain pedal to guitar, vocals and almost any other suitable sound source. Rather than simply adding an effect to the input signal, the newly developed Spectral Sampling Engine captures tonal components of the played note in real time and holds them when desired. The result is flowing pads, long-ringing chords and multi-layered soundscapes while you keep playing on top.

Spectral Sampling Engine

Spectral Sampling technology takes into account not only pitch but also the dynamics, overtones and individual character of the input signal. This preserves the properties of the connected instrument within the sustained layers. The PLUS Pedal II is therefore suitable not only for electric guitar and bass, but also for vocals, acoustic instruments, wind and string instruments and experimental sound sources.

Auto Layer Catch and Infinite Mode

A key new feature is Auto Layer Catch. While the pedal is held, the engine detects newly played notes and automatically adds them as further layers – no repeated manual triggering required. The LAYERS control sets whether one to ten layers are built up. For extensive soundscapes, an Infinite Mode with continuous layering is also available.

Brass Pedal with Gradual Optical Control

The distinctive brass pedal uses gradual optical control. Sustain is not simply switched on or off but can be controlled continuously depending on the pedal position. This brings the feel closer to the damper pedal of an acoustic piano and allows organic transitions between sustained and dry signal.

Sound Shaping with Rise, Decay, Tone and Resonance

LEVEL, LAYERS, RISE, DECAY, TONE and RESONANCE provide extensive sound-shaping options. RISE and DECAY affect the attack and release of the generated layers, while TONE and RESONANCE shape their character. The Dual Resonator function can generate upper or lower harmonic resonances that evolve dynamically with the active layers. A circular display with eleven LEDs shows layers and operating states at a glance.

Smart Stereo FX Loop

The pedal is particularly flexible when integrating external effects. The Smart Stereo FX Loop features a three-position routing switch that places connected effects before the PLUS Pedal engine, inside the processing or after it. This lets you change the signal order without rewiring your pedalboard.

Instrument and Microphone Input, Stereo Connections

In addition to the 6.3 mm instrument input, the PLUS Pedal II features a combined XLR input with built-in microphone preamp offering up to +27 dB gain. Dynamic microphones can be connected directly; phantom power is not provided. SEND, RETURN and OUT also support stereo signal paths via TRS connections, and mono operation is possible with TS cables.

Footswitch, USB-MIDI and Firmware Updates

An optional external footswitch can be used for additional control. WET, LATCH and HIDE modes expand the operating options for live and studio use. USB-C also provides USB-MIDI and firmware updates.

From naturally extended single notes and chords to atmospheric pads and complex, constantly evolving soundscapes: the PLUS Pedal II is far more than an ordinary sustain pedal and brings sustain and real-time sampling intuitively into your playing with your foot.

Frequently Asked Questions about the Gamechanger Audio PLUS Pedal II

Which sound sources does the pedal work with?

Electric guitar and bass as well as vocals, acoustic instruments, wind and string instruments and experimental sound sources.

How many layers can the PLUS Pedal II build?

The LAYERS control sets 1 to 10 layers. Infinite Mode provides continuous layering.

What does Auto Layer Catch do?

While the pedal is held, the engine detects newly played notes and automatically adds them as further layers.

Can I connect a microphone directly?

Yes. The XLR input with mic preamp (up to +27 dB) is designed for dynamic microphones. Phantom power is not provided.

Does the pedal work in stereo?

Yes. OUT, SEND and RETURN support stereo operation via TRS connections; mono is possible with TS cables.

Where can external effects be integrated?

In the Smart Stereo FX Loop – before the engine (Pre), inside the processing (Inside) or after it (Post).

What power supply is required?

9 V DC, center negative, at least 500 mA, with a 2.1 x 5.5 mm plug.
