Prismatic Wall

Electronic Audio Experiments created the Prismatic Wall to simulate the sympathetic resonance of instruments like sitars and pianos. Notes you don't play ring out in response to the notes you do.

The circuit uses physical modeling to create virtual 'strings' tuned to a chord that resonate when you play. Choose the chord voicing, and those frequencies add ghostly overtones to your signal. The effect is subtle at low settings, otherworldly when pushed.

Controls include Tune (sets the resonant chord), Decay (how long phantom strings ring), and Blend. An internal trimmer adjusts sensitivity. Works best with clean or lightly overdriven tones where the harmonics can breathe.

Not a reverb, not a synth, something else entirely. The Prismatic Wall adds dimension to guitar that wasn't possible before.
