KORG EA-1 Synthesizer Electribe Released in 1999, this is a classic synthesizer from the ELECTRIBE series, capable of being used as a synth bass like the Roland TB-303, or for creating synth phrases. This listing includes the main unit, AC adapter, and instruction manual. There is some aging, wear, and dirt. (See photos) I have confirmed basic operation with headphones, but I have not checked all functions. Please consider this item if you understand synthesizers, as it is over 20 years old. No claims and no returns accepted.
