Korg Arp 2600 FS

Korg's very-limited-edition remake of the Arp 2600 is 100% a real, full-size 2600 - not a single thing is out of place. Additionally, it includes some modern features that bring it into the 21st century, such as USB, MIDI, and low-impedance XLR audio outputs. Only 400 of these were made, and all were sold immediately.
