High-end overdrive sound with natural tone control. The Over Driveulator (DRV-1) has a similar circuit design to the FOD-1 (the FOD-1 has a mid-boost circuit). The switch allows you to choose between Tight (distortion using silicon) and Loose (distortion using germanium), allowing you to freely control sounds ranging from vintage-like fuzz to impressive high-gain distortion reminiscent of the Demeter TGA-3 guitar amplifier. The tone control is key to this unit. You can freely create sounds from a round, soft, creamy sound to a sharp and edgy sound that never loses its bottom end. The natural and organic distortion is truly impressive. From the clarity of the notes to the way the distortion cuts through, and the range of sound shaping possibilities, this is a top-class overdrive from every angle. Tight/Loose Switching: * Silicon Diodes = Vintage-feeling, amp-like, subdued distortion * Germanium Diodes = Deep, sustained tube amp tone 44,000 yen (tax included: 48,400 yen) Operational check: Power on OK / Sound output OK (Last checked: 12/28) I am selling this because I quit playing guitar shortly after I got it, so I haven't used it much. However, it is a used item that has been in someone's hands, so please refrain from purchasing if you are overly sensitive! The power jack is a mini-plug. Body only. Everything in the pictures is included. Thank you!
