@Don Vitos , just as an example when comparing new, it appears the two brands are in the same price and quality range.
From the F Bass website, new would be $4,000 (
VF Series – FBASS)
Lakland US models range from $3,875 to $4,560 (
4 String Basses - Lakland Bass Guitars)
Your "friend" is not being very friendly with his proposed offer by asking for $$$$ as part of the trade--assuming that both used basses are in similar condition. The pictures of both basses look great (excellent, maybe mint condition), so your bass would have to be non-functioning and his in mint condition to justify his terms.
