Unused since new. This is a germanium-based clean booster. Features: Stable sound unaffected by ambient temperature, a common issue with germanium transistors. This unit is characterized by its musical tone, providing a detailed and smooth sound compared to the original signal, even at unity gain. Its unique compression cannot be achieved with a compressor. Boosting further drives the amp while producing a rich, thick sound with harmonics. It matches not only guitars but also basses, and its unique thickness and exquisite harmonics are one of a kind. It also works well with acoustic guitar pickups, producing a warm, natural sound close to the instrument's acoustic resonance.
