This is a full-range booster with minimal coloration, similar to a micro amp. Recommended for those seeking a unique effect! Boosts up to approximately +20dB. When the knob is turned down to Min, it functions as a buffer, maintaining the same volume as the bypassed signal. When using distortion/overdrive pedals as boosters, you need to consider the pedal's character when connecting them. The Tenor simply boosts gain before a distortion/overdrive, increases volume after it, and pushes the amp's sound. It can also be used as a color-free buffer.
