VHS Reverb pitches the reverb trail down and stretches it — notes dissolve into a slow, pitched, droning mass. No preamp drive; the signal enters the effect clean. Vibe modulation before the VHS Reverb adds rotary-speaker swirl that the reverb then stretches and sustains. LFO on Play Speed means the pitch of the drone slowly shifts over a 45-second cycle. Playing triggers the drone; the drone then lives on its own.
