I've always wanted an old Aria, due to some of my bass influences playing them. Cliff, Neil Murray, Rudy Sarzo etc...
I know that a lot of those guys played the 1000/ elites etc.., but I'm a died in the wool passive kind of chap lol
It's a September 1981 if the serial decoders are correct.
I really enjoy the feel of the neck - meaty without being fat, and quite wide as well but not uncomfortable in the slightest.
