From ENGL:

“The Powerball pedal is tonally based on the Lead2 channel of the Engl Powerball II, recreating the gain stages of the amp itself. True bypass and completely analog, the pedals specially selected components offer up a particularly high level of sound quality. The electronics assembly is protected by a highly durable housing, meaning you get a pedal thats going to deliver for a lifetime!”

Very Good condition, box and power supply not included.
