"The OB-Xa is a classic analog polysynth, with the ability to split and layer its programs. Made famous by Van Halen's "Jump", the OB-Xa can have 4, 6, or 8-voice polyphony depending on the hardware. It is quite similar in sound to the later OB-8, but the OB-Xa has less-stable oscillators - which contributes to its wilder, wider sound. This OB-Xa is configured with 8-voices, and has a selectable 2-Pole or 4-Pole multimode filter and 120 patch memories. It has had the keybed rebuilt, bridge rectifier upgraded, and is fully calibrated. It spent part of its life in a road case with degrading foam, which caused bad pitting in the front and rear panels (see photos); this cosmetic condition is reflected in price. Power cord included. Thanks!"
