This is the tube overdrive pedal from Donner Company with the name of Tube Drive, which is also a pure analog circuit tube chorus pedal. And maybe it’s the smallest analog overdrive effect pedal ever. If you're looking for tube tone without the hassle and cost of a tube amp, check out the Donner Tube Drive Pedal. With 100% pure analog goodness for guitar tone needs, the Tube Drive gives you all the dialing-in and shaping control you want and makes it easy. Although Tube Drive has a small size, it is equipped with complete basic adjustment knob. There are three function knobs, namely VOLUME, TONE and GAIN.VOLUME is used to set the output volume. TONE is to set the effect brightness. GAIN is used to set the gain of distortion. Two models: BOOST 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.
