Description

Lethargy is a fully analog phase shifter built around eight OTA stages. Its built-in low-frequency oscillator offers two selectable waveforms and a very wide rate range, from several seconds per cycle up to 110 Hz. At the fast end of that range the modulation can be used for vibrato effects as well as classic phasing.

The unit also provides three patch points aimed at modular users, allowing it to be integrated into a modular setup alongside other gear.

No further details on controls, audio connections, power requirements or dimensions are given in the available product information.
