The Little Angel is an innovative PT2399-based chorus designed by Rick Holt.
Operation
Like any other chorus, the Little Angel mixes the input signal with its pitch-modulated copy; to achieve this, a delay line (in this case, the PT2399) is employed. Pin 6 (VCO) of the PT2399 is grounded, and the voltage at pin 2 (Vref) is modulated by an LFO.
