Description
The new invention was a neatly designed stomp-box with two 1/4″ jack inputs, separate volume control knobs, a foot controlled fast/slow button, a yellow light for tremolo indication, a red light for power and of course the 6 pin amphenol socket where the Leslie cable was plugged into. Also mounted on the box was a line cord both for supplying the Combo Preamp’s internal circuitry with power and passing power on to the Leslie cabinet through the 6-pin connector. The first model, simply called Leslie Combo Preamp, was made to interface with the type 147 power amplifier.
