Selling to organize my equipment. I purchased this and have kept it in storage after only testing it out. There may be some scratches, but it's in almost-new condition with very little use. Functionally, there's no crackling and it works normally. The items for sale are the main unit, original box, documents, and everything else shown in the photos. This is a distortion pedal known for its high gain and noise-free operation. What this means is that it's a distortion pedal with a lot of sound pressure, but when the input signal disappears, the gain automatically decreases, eliminating annoying noise during silence. When you start playing again, the gain returns to its original level, providing a high-gain sound. It's a sophisticated design. The key to using it is to play strongly or use a guitar with high-output pickups for a smooth experience. How about getting this one? Please note that the current consumption is 150mA, which is considerably higher than a typical distortion pedal, so pay attention to the adapter you use. The condition is as described above, but it's a used item from a private seller. To prevent any issues, I would like to ask that you understand that it is sold as-is, with no returns or exchanges. The price includes shipping, so please understand that I will not offer any discounts. Feel free to buy it immediately. Thank you. [Product Information] ■ X Knob Controls the sound pressure. Emphasizing it results in a heavy low-end rhythm and a sound where each note's picking stands out. ■ Channel Switch Switches between 3 gain ranges. ・ Normal (center): Supports everything from preamp-like use to mild boosts and biting drive tones. ・ Crunch (switch right): Adds a treble boost to the pre-boost section. A clear tone that doesn't over-compress the low frequencies. ・ Lead (switch left): Adds a full-range boost to the pre-boost section. ■ Density Section Changes the density of the sound, enabling more complex sound creation. ・ OFF (center): Supports mild boosts and core drive tones. ・ Density High-Mid (switch right): Condenses the sound density to High-Mid, improving the separation and clarity of each note. ・ Density Low-Mid (switch left): Shifts the sound density to Low-Mid, adding thickness and a sense of weight to the sound. ■ Power: DC9V center negative, current consumption 150mA * Does not support battery operation
