※ Final price reduction. This is the distortion pedal "Adrenaline" (C9H13NO3) released by the Japanese effects pedal brand KarDiaN. No box, just the pedal itself. Purchased about a year ago at Ishibashi Music in Shibuya. It was sold without a box from the time of purchase. I've used it several times in live performances, so please understand that there are some minor scratches, but it works perfectly. When plugged into a tube amp with a humbucker guitar, you get a thick, stoner rock-like distortion, just as described in the product description. When used with a single-coil guitar, it produced a gritty distortion with characteristic low frequencies. It's a great pedal with a unique texture that you can't get from modern distortions. ※ Quoted from the official website below - SPECS - • Input Impedance: 1MΩ • Output Impedance: 10kΩ • Controls: Volume, Drive, Treble, Bass • Switching Method: True Bypass • Connections: 1/4 inch standard phone jack x 2 (input, output) • Power Supply: 9V center negative DC power supply (9V 006P type battery also acceptable) • Current Consumption: 6mA • Dimensions: Width (W) 72 mm, Depth (D) 121 mm, Height (H) 55 mm (including protrusions such as foot switches and jacks) • Weight: 285g - Product Description - Retail Price: ¥38,500 A dry distortion reminiscent of Japanese fuzz. Desert rock was born in the deserts of California in the 80s. The guitar sound, as if running through the vast desert, was heavy and incredibly dry. The development of "C9H13NO3 / Adrenaline" started by breaking away from the idea of being "amp-like," rather than the silky distortion of modern high-gain amps or the rough distortion of old stack amps. While maintaining a wide dynamic range, excessive bass and treble are spoiled, and while having modern fineness, the roughness is not eliminated. The result is a distortion with a dry quality similar to vintage Japanese fuzz and an exquisite roughness that doesn't over-compress the distortion.
