Electro-Harmonix Riddle: Qballs

Electro-Harmonix Riddle: Qballs


This is HornFX’s favorite envelope filter that EHX produces. It is a complete and solidly designed pedal that produces great auto-wah funkiness with an easy and intuitive interface. It boasts some fantastic controls that will give you a lot of fun options for funky sounds. Sadly, the distortion function might not be a workable aspect of this pedal due to what will most likely be feedback issues. Plug this pedal in, explore, and get funky.
