The Mooer Mod Factory Pro Twin Modulation Pedal is constructed by combining 2 high performance digital modulation engines into one compact unit. The Mod Factory Pro provides a wide range of different modulation effects between the two modes A and B. The 2 different modes have their own set of Speed, Depth and Control knobs, as well as a rotary selector to choose between the effects and then fine tune them. The Mode A and Mode B can be operated separately or simultaneously, and the signal chain routing can be adjusted using the Routing Switch. The signal chain can change from Serial Mode A to Mode B or visa versa, providing the artist with a wide array of tonal possibilities.
