Sound output confirmed. Fully functional. Used a few times at home, with slight wear on the lettering, but I think it's in relatively good condition. Please check the details in the images. Around 2008, this is an overdrive pedal from NK ROCK SOUND, a handmade guitar effects pedal brand that was making pedals individually, in the style of the Klon Centaur and landgraff. They are no longer making pedals, so this is a valuable item. Body only. *The product was photographed with a smartphone. The color and condition may differ from the actual product. In addition, there may be stains, discoloration, dullness, scratches, and scuffs that are not visible in the photos. *No smoking, no pets.
