This pedal is officially described by the manufacturer as directly sampling the preamp of a hand-built 36W Class A vacuum tube amplifier. Some say this pedal captures the sound of a "BRUNO UnderGround 30" type amplifier. The item comes with the main unit, box, manual, etc., as shown in the photos. The main unit appears to be free of scratches. Individual judgment criteria vary, so please assess the condition based on the photos. I believe the functionality is not an issue. It has been stored in a smoke-free and pet-free environment. Below is the web information for this pedal: Sound Character • Blue Channel: Transparent, three-dimensional, and silky clean to crunch → Compatible with jazz/blues/clean-focused playing • Red Channel: Thick mid-range, harmonically rich natural drive → Boutique amp-like responsiveness and stickiness The distortion amount is not high-gain, but rather clean to medium gain. Recommended for: • Those who like the glossy clean/natural drive of boutique amps • Those who want to create a small board/amp-less environment • Those who prioritize sound quality and responsiveness over high gain Thank you for viewing. Thank you.
