This is the booster pedal from Donner Company with the name of Booster, which is also a pure analog circuit booster pedal. And maybe it’s the smallest analog booster effect ever. The Booster pedal could create the rich distortion sound, and make it more powerful. By adjusting the GAIN knob you can get a full frequency boost that is transparent and gives you back what you put into it. It would be easy for you to design own guitar sound in different live performances. Although Booster has a small size, it is equipped with complete basic adjustment knob. There are three function knobs, namely TONE, VOLUME and GAIN. VOLUME is used to set the effect output volume. TONE is to set the effect brightness of tone. GAIN is used to set the gain of boost. Two models: MID and NORMAL. True bypass switch lets your instrument’s signal pass through a non-electronic bypass line when the effect is disengaged, feeding your amp with direct, unaltered signal from your instrument.
