Electronic Audio Experiments Prismatic Wall Sympathetic String Resonator Pedal

The Prismatic Wall is not just an effect. It’s a living, breathing harmonic field that responds to your playing with ghostly resonance and shimmering overtones. Designed by Electronic Audio Experiments, this pedal creates the illusion of sympathetic strings vibrating in tandem with your signal, like a spectral harp hidden inside your amp.

It doesn’t distort or delay in the usual sense. Instead, it builds a harmonic scaffold around your notes, letting you sculpt ambient textures, cinematic drones, and otherworldly feedback loops. Whether you’re chasing post-rock swells or experimental soundscapes, the Prismatic Wall turns your signal into something alive.

Special Features

• Sympathetic resonance engine that reacts dynamically to input signal

• Organic feedback paths for evolving textures

• Designed for expressive, non-linear soundscaping

• Works well with reverb, delay, and modulation pedals

• Built for experimentalists, ambient artists, and sonic explorers
