I purchased this used over six months ago, but I'm selling it to cover guitar repair costs. Operation confirmed, box included. No Velcro on the back. I do not have pets, and I do not smoke. The preamp section is particularly excellent, enhancing clean tone sound-making by adding a certain degree of compression while providing an amp-like saturation feel. Power: 9VDC (power supply sold separately, center negative) Current consumption: Max 83mA The Crossfire reflects one of the most classic pedal-amp combinations in guitar history! The green mid-hump overdrive we've come to love meets a blackface amp with a beautiful, rich clean sound. We chose to accurately reproduce the classic overdrive circuit but added some of the most common modifications seen over the years. The clipping toggle switch allows you to select between symmetrical (original) or asymmetrical. Asymmetrical clipping improves touch-sensitive drive characteristics. The gain toggle switch increases gain and changes the low-frequency response. The all-analog circuit, which follows the path of a blackface tube amp, provides authentic amp tones and feel. It features a full EQ section with a glassy, slightly mid-scooped clean sound. The headroom switch allows you to select high headroom solid-state rectified 4x6L6 power amp, or low headroom and sag with tube rectification and a low-wattage 2x6L6 power section. The passive effects loop allows you to connect your favorite pedals between the overdrive and the amp-in-a-box to build your ideal rig.
