The BitQuest is a compact, multi-effects pedal featuring 8 fun and adventurous patches that can be used with or without a built-in digital fuzz. The patches on hand include a full featured flanger, high pass and low pass filters, a bit crusher with sample rate reducer, an infinite reverb, a deep notch filter, a ring modulator with reverb, a +/- 1 octave pitch shifter, and a wild glitch delay. Like all Dr. Scientist pedals, the BitQuest can be used with guitar, bass, synths, and many other instruments.

What does the side jack do?

The side jack is for an expression pedal input.   The pedal you plug in will take over for the CTRL1 knob.

Does my dry signal become digital?

No, the dry signal path remains analog.  Only the effected signal goes through analog to digital conversion.

What kind of expression pedal can I use?

You need to use a passive (no power) expression pedal with a TRS cable, 10k to 100k Ohms resistance.

How do I switch between Fuzz and Clean modes?

There's a special little process to change modes on the BitQuest, the computer inside needs this reset to load in the new bank of patches:  Click the toggle to either Fuzz or Clean, turn the Patch Selector off the current patch.  Be careful with your volume going from clean to fuzz, the fuzz side can be loud!
