filter fine-tuned for guitar frequency response.
Sculpt your envelope to reveal a truly expressive tone, with a defined and
unique signature. Riddle will deliver tight and smooth control over the complete
80 Hz to 5 kHz range, with a consistent and even sweetness.
Need some edge? Engage Riddle's analog distortion and dial in anything from
subtle bite to dominating crush.
You can even plug in an optional expression pedal to control the filter sweep
with your foot. With the ability to adjust Q, sweep range, and filter type,
you'll also wind up with of the most versatile wahs available.
Riddle: a mysteriously musical envelope filter for guitar.
We can add a DISTORTION knob on the right side of the box if you want to be able to control the distortion
without opening up the pedal. It's a $50 mod.
Uses 150mA so it won't run on a low current output like a normal pedalpower2 output. Should be fine on a 200mA output.
