Burford Reefer "Coral Sitar" Emulator (really a Green Ringer) on a Casio AT-40 Arabic Keyboard

video upload by Edward Jones

"The rectifying octave up of the Green Ringer style circuit sounds frankly amazing on the analogue sine-based drum tones that the drums on AT-40. We were not expecting it to sound so cool. We were in "Flavour Country".

If you want this sound on your own tracks, I highly recommend 'Gringer' by Chris from Airwindows. He's made a model of the rectifying part of the circuit. To get the full 'Reefer' experience, place a warm overdrive on the way into Gringer to emulate the first stage of the Reefer pedal.
