Few envelope filter effects pedals can come close to the tone-shaping power and precision that the Riddle: Q-Balls For Guitar brings to the table. This envelope filter pedal from Electro-Harmonix lets you dial in some truly expressive and funky tones using adjustable Q, sweep range, and filter type. Plug in an expression pedal and you get even more control over the Q frequency’s sweeps. There’s also a dedicated Distortion effect that can dish out everything from a subtle bite to an all-out crush.

    I have to say that this pedal is aptly named Riddle because achieving that classic envelope wah is very tricky. It’s also crowded with controls that some may find rather unusable.
