SUPREME ROTARY-SPEAKER SIMULATOR:
 
From the Beatles to Jeff Beck, Santana to Stevie Ray, many guitar greats have incorporated the rotary speaker into their rigs. With this in mind BOSS proudly presents the RT-20 Rotary Sound Processor. Employing COSM-modeling technology, the RT-20 authentically reproduces classic rotary-speaker sounds. It offers adjustable Rise Time, Horn and Bass speed, Overdrive, and more. And not just for classic twirl, the RT-20 can be used to create unique overdrive and pulsating effects as well. This pedal sounds amazing, and offers a stunning graphical view of the virtual rotors on its built-in display.

Upon testing, I found that this unit only works powered with  an AC/DC adaptor. Unfortunately, it doesn't work with batteries installed. It could be a spring in the battery compartment has come loose or damaged. Kindly be informed.
 
Batteries and AC/DC adaptor are NOT included in the sale. Kindly be advised.
