Introduction
The StonZ 2440 is a classic four stage phase shifter, enhanced with voltage controlled functions such as center
frequency, regeneration and modulation depth. A wide range low frequency oscillator (LFO) is built in. External
modulation may be applied to the Frequency jack or the Ext Mod jack, which is mixable with the internal LFO.
Regeneration is phase switchable, allowing a “classic” sound as well as an extra bright phasing effect. The
regeneration control allows self oscillation at maximum rotation.
Two out of phase outputs allow stereo imaging with the classic “moving sound” effect.
This design offers lower noise and larger signal handling than traditional circuitry.
