I have a black 5-string Aria Pro ii bass I am looking to sell, along with a good padded gig bag. Any ideas as to how much it is worth? Ideally I am looking for £200 inc. the gig bag at least, can I be any more optimistic without being cocky? The bass is in excellent condition, but I have owned it for 4 years and do not know if it were new when I got it. Any help / offers greatly appreciated Thanks guys
