Same feeling of the original tonewheel organs' pedalboards. Just shorter and lighter. Just 18 notes. For gigging musicians. Expression pedal is included and if you play it with a Legend or a Legend Live you don't need a power supply (sold separately), the pedalboard is powered via midi cable. The Pedalboard 18 is a MIDI pedalboard, so you can use it with other brands of MIDI instruments as well.
