SKU: FPI-P Category:


The Fusion Preamp Interface Pedal, designed for connecting and controlling Leslie® speaker cabinets, enables simultaneous operation and safe speed switching. The built-in preamp provides 26db of clean gain volume, treble and bass controls while the 11-pin connector provides the signals and speed control from the organ.

In addition to the 11-pin connector, Fusion features a 1/4″ input for guitars as well as other keyboards or electronic instruments. A low cut switch is useful for acoustic guitars, too. The gain select switch allows you to vary low or high gain to suit your application.

The 147 output connects to a Leslie 147 or 145 style rotary speaker and the 122 output connects to a Leslie 122 or 142 style speaker.

The Fusion Pedal features a conveniently shaped “stomp box” enclosure with rugged switches for foot control of speed and mode. This variation also includes MIDI for controlling speed and stop, as well as “recording” speed switch movements during play.
