From the vendor
The Celeste Chorus is a direct clone of the 70’s EHX Clone Theory (MN3007 edition) traced from original units and corrected against schematics and flawed projects available online.
The only additions are extra power filtering, a charge pump & regulator to achieve the required 15V of the original circuit from a standard 9V DC power supply, and an added output booster for the well-documented volume drop of the circuit.
New as of version 1.2: Added mod for high output pickups!
