Riddle: Q-Balls envelope controlled filter for guitar! This is a very powerful tool for musical expression that opens a new horizon of sonic potential for your guitar. Please take a few minutes to familiarize yourself with the Riddle’s controls and how they work.

Envelope controlled filters are a unique type of sound modifier where the intensity of the effect is controlled by the user’s playing dynamics. The volume and dynamic of the incoming audio signal is used to control a swept filter. As the volume increases or decreases so does the frequency of the filter.

With 3 selectable filter modes, along with START, STOP, ATTACK, DECAY, Q and SENSITIVITY controls, all of the classic Q sounds are available to the user. Also, many new sounds and vivid textures can be achieved like never before. A new analog distortion circuit was created specifically for the RIDDLE, and adds a dynamic edge to the filters sound. With the addition of an expression pedal input (expression pedal not included), the RIDDLE provides manual control of the filter sweep.
