Electro Harmonix Riddle Q-Balls for Guitar

Can you solve the Riddle?

The Riddle is a complex envelope filter specifically designed for electric guitar. This fully analog effects unit is extremely interactive with the player; unique styles and picking dynamics shine through and heavily impact how the Riddle sounds. Combine that fact with the myriad of controls which are all interactive, and you truly have one complex Riddle to solve.

Great for that Quack-Quack Auto-Wah sound, or to produce long, sweeping, synthesizer textures and so much more! You can even plug in an expression pedal for additional control. The Riddle also features a perfect and very complimentary distortion circuit.
