Dr Scientist · pedal
The Dr. Scientist Frazz Dazzler V2 is the updated version of the original Frazz Dazzler dual-channel fuzz pedal from Canadian boutique manufacturer Dr. Scientist, handmade in British Columbia. The V2 retains the dual-channel architecture, active three-band EQ, voltage starve system, parallel Mix control, and high-gain noise gate of the original while refining the circuit and expanding control options. The expression pedal input allows real-time control of the Mix parameter, enabling dynamic fuzz depth adjustment. The V2 builds on the proven platform of the original and is the current production version of the Frazz Dazzler, suited for guitar, bass, and synthesizer.
What stands out
“The active three-band EQ retains its power to sculpt fuzz character well beyond the capabilities of passive tone controls common to the category”
