haha meow is a clone of the roland funny cat, a true gem of the 70s severely under-celebrated. two circuits create the sound of haha meow, a harmonic mover and a soft distortion sustainer. funny cat, and subsequently haha meow, is perhaps the most unique envelope filter and fuzz combination to ever hit the market. while keeping the original circuit fully intact, yesterday effects has added a master switch in order to turn both effects on/off with the option to bypass the circuit’s buffer. three controls rule over the sound of haha meow: a volume for the soft distortion sustainer, and for the harmonic mover there's a blend knob and a three way rotary.
