This is a device that simulates the architecture of the Alesis QuadraVerb, a classic rack-mounted reverb unit from the late 80's that has four effects: reverb, delay, pitch and eq.
The audio chips of that era had a limited bandwidth, so the sound has it own character. So far I didn't try to emulate that particular characteristic, instead I went only for the effects and a little bit of saturation. It can produce some wild sounds.
The signal goes: EQ → Chorus (pitch) → Delay → Reverb → Saturation → Output
Side-note: It was the main reverb in my album Path.
