  • Compact and durable die-cast construction
  • True bypass preserves signal integrity

Cons

  • Fixed vintage circuit may lack versatility compared to boutique multi-mode fuzzes
  • Requires external power or battery swap, no USB-C or rechargeable options

Setup, Compatibility & Care

To integrate this pedal into your rig, connect your instrument to the input jack and your amplifier to the output jack using high-quality patch cables. If using an AC adapter, ensure it is a standard 9V center-negative power supply to prevent damage. For maintenance, keep the chassis clean by wiping it with a soft, dry cloth. To extend the life of the internal components, disconnect the input cable when the pedal is not in use to avoid unnecessary battery drain. Avoid exposing the pedal to extreme moisture or temperatures to protect the vintage-style electronics.
