Top effects pedal maker Electro-Harmonix has unveiled a pair of brand new envelope filter pedals for guitar and bass.

The Q-Balls Riddle and Enigma pedals are fine tuned to the specific frequency response of each instrument as well as including an analogue distortion circuit.

The funky sounding pedals have been designed by EHX collaborator Mike Beigel (the brains behind the MU-Tron III, Q-Tron and Bi-Filter), and judging by the videos below will continue EHX’s tradition of weird and wonderful sounding pedals!
