  • Excellent condition. Light wear, gently used.
  • Electronics fully serviced and restored. Volume control replaced, rewired all components.
  • Takes one AA battery to achieve the low voltage ultimate crunch sound. Cannot use a power adapter.
  • Missing 2 tiny screws out of 4 for the bottom plate, but 2 hold it just fine and they wouldn't be hard to replace
  • Amazing pedal!
