This is a great-sounding chorus pedal with simple depth and rate controls and a 3-position toggle that allows switching to flanger and pitch modulation modes. There are mono and stereo outputs. It is a rare example of the initial run of EBS pedals built in Sweden in 1998, long before production moved to China. These early pedals had gray cases and reversed jacks (input on the left, output on the right). This pedal is in excellent-plus condition, with no dents, dings or Velcro residue and only a few small surface scratches. It takes an internal 9V battery or a standard 9V center-negative adapter (not included). It comes with manual and non-original box.
