"This is the tremolo pedal from Donner Company with the name of Ripple, which is also a pure analog circuit tremolo pedal. With 100% pure analog goodness for guitar tone needs. Although Ripple has a small size, it is equipped with complete basic adjustment knob. Classic tremolo effects with a huge range of speed and depth. There are three function knobs, namely DEPTH, COLOR and SPEED. DEPTH is used to set the effect depth. COLOR is to set the effect brightness. SPEED is used to set the effect speed. Two models: MOD 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."

This pedal is in very good condition with some wear. There is velcro on the back for mounting to your pedalboard.
