This pedal is ideal for playing organ or keyboards while sitting on a bench or stool. Thanks to the two buttons on the side of the pedal, the speed of the rotary effect can be switched hands-free. The EXP-20 is made of solid plastic on a solid metal base. Two long TRS (stereo jack) cables are included. The EXP-20 can be used with your Mojo and also other keyboards if it is compatible. The friction (movement) of the pedal can be adjusted.
