From the vendor
Clone board of the Last Gasp Arts Sick Pitch King Jr. Very sick indeed, like the nastiest tone knuckle ball you've ever heard. External expression pedal input is also available for the frequency control, which via a toggle, can be smooth or stepped in nature. A tone strike that will catch you looking, every time. Uber-cool!
