Zon Sonus Special fretless 4 bass, exceptional neck and fingerboard with satin finish. Made in early 1990's (exact date uncertain). The bass in is outstanding condition for its age. The fingerboard has subtle lines, so it appears unlined from a distance. Neck is slim taper and very fast player. Ash body with bubinga top, gloss finish. Bartolini hum cancelling J pickups and 3 band preamp. Excellent construction quality, tone, and playability, and light weight at about 8 lbs. Only selling because I want to replace the bass with a 5 string fretless. $1900 and free shipping to the continental USA. Ships in original HS case with ZON logo.
