Reverb and vibrato effects with vintage aesthetics

The Vongon Ultrasheer is a stereo pedal that combines reverb and vibrato, inspired by the early digital studio effects of the late 1970s. With its simple and engaging interface, it allows you to range from deep, modulated rooms to drier, more contained rooms.

Stereo reverb inspired by the Lexicon 224

The Ultrasheer's reverb is inspired by the famous Lexicon 224 from 1978, recreating a warm and enveloping digital plate sound. The digital section is deliberately reduced to 16 bits, following the topology described in Dattorro's famous paper, to achieve a blend of vintage aesthetics and current performance.

Transparent digital vibrato with double modulation

The vibrato section offers smooth and transparent digital pitch shifting that preserves the full range of the input signal. You can choose between two modulation waveforms: "cycle" (sine wave) for Leslie-style effects, and "random" (smooth sample & hold) to simulate the effect of warped vinyl or a cassette tape in the sun.
