Analog Outfitters' "The Scanner" uses old-world technology from repurposed Hammond organs to create breathtakingly luscious reverb and vibrato effects. Recycling the actual vibrato scanners and reverb tanks from the old tonewheel organs, Analog Outfitters actually improved upon the original design with a new DC brushless motor, audiophile electronics, footswitchable modes and "Gas Pedal" expression which lets you ramp up the speed of the vibrato with a standard expression pedal.
